Bulk PCB Assemblies

PCB design and manufacturing is a complex and exhaustive process. With the introduction of new types of materials and technologies, the cost of PCB fabrication and assembly is shooting up. Engaging with a contract manufacturer for a small build volume turns out to be an expensive deal. To keep up with the growing costs of PCB development, ordering PCB assemblies in bulk can be a huge advantage. The count here we imply is in thousands and above. Automation of the PCB assembly process is profitable when there is such mass production. Also, the assembly and testing time will reduce significantly.

As the PCB development proceeds from prototype to production, the build volume also increases. A prototype is assembled in counts of tens or hundreds only. The production volume picks up once the design is approved for final production with the necessary certifications. You have to evaluate the market requirements and plan for manufacturing in one go. This will help in increasing the PCB assembly line efficiency. Bulk component procurement can fetch good discounts from vendors and also helps in rapport building.

Several industries like communication, automobiles, and aviation are in continuous need of new products. Assembly and testing PCBs in big volumes can help OEMs maintain their ‘time-to-market’ plans efficiently. This boosts the brand image and customer loyalty. The merits associated with the bulk ordering of PCB assemblies are many. Read further to know them in detail.

Advantages of Ordering Bulk PCB Assemblies

1. Cost-effective solution

The primary benefit of bulk ordering is the reduced PCB assembly cost. The per-unit cost comes down drastically as the components are purchased at wholesale prices. The non-recurring engineering charges become cheaper as the assembly line setup is established only one time for the complete big volume. The inspection and test apparatus run simultaneously with the PCB assembly, hence improving the line efficiency. The cost difference gained as compared to small-volume builds can be effectively used for competitive product pricing in the market.

2. Rapid turnaround time

In the PCB assembly process, some components may get damaged during manual handling. But if components are bulk ordered, there will be enough parts to assemble the first batch without losing time on repurchasing. At wholesale rates for bulk orders, you can buy surplus parts to cover such shortages. Also, the service provider can adopt an automated assembly process if there is enough build volume. This assures faster turnaround time and quick project delivery.

3. Reliable product quality

All the PCB assemblies must have consistent performance. Process automation can fine-tune the assembly line settings for optimum output and is economical for mass production. Each PCB assembly goes through the same quality and testing procedures, resulting in uniform production. Automation reduces the chances of defects and failures in the final product. PCBs built in large volumes undergo X-ray inspection, on-board tests, etc offering steady product quality.

4. Design Customization

One of the significant advantages of bulk ordering is to get customized services from the assembly provider. You can add specific components, modify board size, or choose unconventional box-building, suitable for your customer usage. With larger quantities, your contract manufacturer can easily accommodate any product changes or iterations based on the market requirements and customer feedback. This is possible mainly due to the high build volume. In small-quantity PCB assembly, such flexibility will not be feasible for your vendor.

5. Better Supply chain management

Procuring parts in bulk establishes a good bonding with the component vendors. They may prioritize your order and offer a stable supply of components for your product assembly. Even they may fabricate a batch of specialized parts for you when it is a bulk order. Inventory management is streamlined and administrative overload will reduce when all the materials are purchased in one batch than in small quantities. It allows good control over the available stock and supports prompt order processing. Thus, the supply chain management becomes more robust and reliable.

6. Scalable to meet customer demands

Product scalability is crucial to meet the increasing market demands. Once your contract manufacturer completes a bulk order successfully, you can be well assured of upscaling the PCB production. High-volume PCB assembly saves both time and effort of bulk build orders. You can achieve maximum profit with ready-to-ship PCB assemblies in stock. Electronic appliances and gadgets are consumed in large volumes today. You can grab the market and meet deadlines by choosing bulk-volume PCB productions.

7. Minimizes risks of component obsolescence

In the electronics industry, often new components are introduced and old parts are made obsolete. This fluctuation in the market can affect the pricing and availability of electrical components. If you have procured surplus parts in your bulk order, you can mitigate risks and fulfil your PCB assembly orders without delays. Through wholesale procurement, you are shielded from unexpected price hikes. This offers long-term cost stability for your budget planning.

8. On-demand product delivery

Bulk ordering supports faster time to delivery of the PCB assembly. With enough material stock in storage, you can assemble the product and deliver it on demand. It enables efficient production planning, minimizes build costs, and ensures timely delivery of products to the customer. This is beneficial for OEMs to stay ahead of the competition.

Ordering bulk PCB assemblies can be valuable in reducing the environmental impact also. By ordering large quantities, you can save on packaging material and shipping costs. This will reduce waste generation and improves resource optimization. So bulk PCB assembly promotes sustainability in the electronics manufacturing industry.


If your PCB product is completely evaluated for functionality and ready to go for mass production, then ordering for bulk PCB assembly can be highly beneficial. The top merits of bulk PCB assembly are cost savings, quick turnaround time, consistent product quality, and customization. With large-quantity components procurement, you can streamline your supply chain effectively. Bulk PCB assembly assures scalability with growing product demand in the market. Extra components procured can be helpful if sudden cost changes occur in the market. Further, you can build PCB assemblies on demand if the necessary inventory is in place. Thus, bulk ordering of PCB assembly is a strategic method to stay competitive in electronics manufacturing.

Top common mistakes to avoid while placing PCB assembly order!

By | Date posted: | Last updated: May 23, 2023
PCB Assembly Order

In the fast-paced electronics industry, new products and features are added to the market every day. To stay ahead of the competition, you have to launch your PCB products on time. Avoiding common mistakes while placing the PCB assembly order is crucial in maintaining the delivery schedules. Several checkpoints in the PCB design process can ensure a high production yield. You have to follow design specifications, place components strategically, implement Design for Manufacturability (DFM) guidelines, and share the latest Bill of Materials (BoM) with your Contract Manufacturer (CM). Building trust with your CM is a key aspect during the PCB fabrication and assembly process.

You can generate quotes from different vendors and compare the pricing before finalizing the right CM for your product manufacturing. The PCB fabrication cost depends on details like board dimension, the number of layers, surface finish, and design complexity. Do you need PCB fabrication along with assembly? Will you procure the components or the CM has to source from your BoM list? What is your lead time for getting assembled PCBs? All these questions have to be answered before going ahead with the order placement and collaboration with a contract manufacturer.

Small mistakes in PCB assembly, especially during bulk orders can cause significant time delays and budget overflows. The degraded performance of the product will also affect the brand’s reputation. Hence, it is important to avoid these common mistakes while placing PCB assembly orders.

Common mistakes to avoid while placing a PCB assembly order:

1. Do not choose a CM without evaluating their competence

There are many contract manufacturers available in the PCB industry today. Without rushing to place an order, you have to explore the services and pricing offered by multiple CMs (Contract Manufacturer). You can visit the assembly house to understand their process quality and technical capabilities. Based on your product market, choose a contract manufacturer with relevant industry certifications. An experienced CM can effectively perform component analysis, review designs, and check for product integration. Take time to compare and then decide the best service provider for your PCB assembly.

2. Do not share partial or inaccurate BoM

If you are asking your contract manufacturer to source the components for PCB assembly, then double-check the BoM before sharing. It has to be complete and up-to-date. If you have missed any component details in the BoM then the CM may procure a wrong part, affecting the board performance. The longer lead-time components used in the design should be highlighted for early ordering. Check for obsolete or ‘End of Life’ components in the BoM and replace them with ‘in-production’ parts. Do not forget to share your approved vendor list with the CM. This will avoid sourcing counterfeit parts.

3. Do not skip PCB design reviews which are essential for high-yield optimization

Along with the functionality review of the circuit design, check if the Design for Testing (DFT) and Design for Assembly (DFA) guidelines are implemented. Missing these recommendations during PCB design will reduce the assembly output. Silkscreen should be readable on both sides of the PCB. Include fiducial markers on the board to assist the pick and place machine during component assembly. Provide edge clearance on the PCB for mounting equipment to get enough grip. This is mandatory for a successful PCB assembly.

4. Do not provide incompatible design output files

Communicating clearly with your CM is highly essential to avoid confusion or delay in the PCB manufacturing services. There are different design output files like Gerber files, IPC 2581, and ODB++ used for PCB fabrication. For Assembly, BoM and X-Y placement files are required. BoMs (Bill of Materials) should be reviewed and shared in standard templates. Schematics and assembly drawings are also part of the design output bundle. It is necessary to provide these files in the formats accepted by your CM.

5. Do not handover ambiguous assembly instructions and testing documents

Provide clear PCB assembly instructions for component mounting sequence, orientation, and soldering techniques. If special components are used in the design, then add associated handling procedures to the document. For example, including the details of EMI-sensitive components and their shielding circuits can save component failures post-assembly.

The PCB assembly document package consists of test specifications and regulatory requirements. Test procedures and expected results must be clearly explained in the test documents. All the assembly documents should be revision controlled for traceability.

6. Do not miss to verify the PCB assembly quality before reordering

Do not opt for low-cost services. It is a common mistake to overlook quality over cost. But this will backfire in the long run. Assess the PCB assembly quality after the first batch output. The PCB assembly should pass the required tests and conform to industry standards. PCB assemblies of inferior quality will result in performance failure. This will add to the debug and rework costs, along with a delay in the delivery.

There are ways to reduce the PCB assembly cost through prior planning. If you are looking for a shorter lead time, then the price will shoot up. Also, the quantity of PCB ordered will impact the assembly cost. CMs will charge for creating soldering stencils, programming devices, preparing test setups, and board inspection. Choosing standard PCB sizes and common materials can help to reduce fabrication and assembly costs. While generating a PCB assembly quote, you must consider all the above aspects. Once you decide on the contract manufacturer, go through the quote in detail and understand the pricing and services offered.


To achieve maximum assembly output, you have to plan and then place the PCB assembly order. Avoiding the common mistakes listed in this article guarantees a smooth and efficient run of the PCB assembly process. The key factor is to evaluate and choose the right service provider. Keep in mind to share the complete and updated BoM. Review your circuit design thoroughly and implement DFM guidelines. As you focus on cost-reduction methods, do not forget to verify the assembly quality before placing your next PCB order.

Top Techniques to reduce the cost of cable assembly manufacturing!

By | Date posted: | Last updated: March 1, 2023
Cable Assembly Manufacturing

Custom cable assemblies, an important aspect of industrial projects, are also known to add to a sizeable portion to the overall costs. Often times cable assemblies need custom designs that can be complex and cost saving therefore involves a strategic identification of opportunities.

Here are some aspects to be mindful of, to be able to optimize costs.

First things first, even before we get to the cost, it is imperative that a detailed bill of materials (BOM) be available. It is a careful analysis of this document that can lead to cost saving suggestions. Additionally, a full specifications list must be available. Once again a thorough evaluation of the specifications can suggest areas of cost optimization without impacting the quality.

What are the techniques used to reduce the cable assembly manufacturing cost?

#1. Make sure that the design isn’t over-engineered & components aren’t over specified

It is imperative to choose the right design that lends itself to ease of manufacturability as also to cost optimization.

Making the choice of the right raw materials is extremely important basis the design. Importantly, the choice should be made because of the right reasons. Sometimes the choice is made simply because of familiarity with certain components or the fact that the components are top-of-line. The fact remains that components need to be chosen based on the bespoke requirements of the project. If, for example, the cable needs to be used in an environment where the temperature is high, due attention must be paid to how high the temperatures are likely to be. Over specifying the components can significantly add to the costs without giving you any tangible benefits.

Also explore more information about Circuit Board Component Placement.

#2. Choose the right connectors

Speaking of components, due care must be taken to choose the right connectors. For this, it is important to understand the transmission that the assembly will handle. Different types of connections require different methods, which in turn have cost implications. You need to make sure that the chosen technique works well for product quality while optimizing costs.

#3. Make the right choice of cables

Assessing your transmission needs is key. If you are looking for regular transmission you can opt for unshielded cables. However, if you specifically need to cancel electromagnetic noise you should go for shielded cables. Using shielded cables where unshielded ones can make the cut, can lead to an unnecessary increase in costs.

#4. Choose the right conductor size

It is also important to choose the right conductor size. Typically, the smaller the conductor size, the lower the costs. Of course, the size has to be chosen in a manner that doesn’t impact quality.

A thorough evaluation of the design could offer you areas of change that can significantly reduce costs without compromising on performance.

#5. Optimize supply chain management

With a professional PCB supplier, You will be able to save costs on the supply chain. For instance, the supplier could be ordering components in bulk and therefore driving down prices on account of economies of scale. Similarly, your supplier could produce a few months’ worth of cables and send them to you as they are required. Building trust with the supplier plays a strong role here.

You also need to ensure that the supplier is great at customer service and acts like a partner in the project.

#6. Choose the right partner

When you are outsourcing complex custom cable assemblies, it goes without saying that the right partner can make or break the project. The ideal partner will help you bring down the cost through:

  • Due advice on design & component selection. With access to industry best practices the partner will ensure prudent selection
  • Creative sourcing of parts that will keep costs under check.
  • Due quality control measures which ensure, that there aren’t costly errors to pay for at a later date.
  • Robust testing goes a long way in ensuring that there aren’t corrections to be made later that result in huge costs on account of wasted time, manpower & material.
  • Robust customer service including speedy resolution of issues, if any.

To sum up

While you need to optimize costs you cannot do it at the expense of non-existent quality control mechanisms. In taking the cost quotations from the partner, ensure also that you can vouch for their quality control process. It is imperative that the partner has an unstinting focus on delivering high quality at the most cost effective price points. Their long-standing supplier relationships can ensure that they are able to procure parts at optimal prices. Additionally, with their expertise & access to industry best practices, they can make sure that you do not need to re-invent the wheel. Their robust customer support team could also help in making sure that each project is delivered seamlessly.
