OEM PCB Manufacturer

Before we look at some of the tips and processes applied by OEM PCB manufacturer for best PCB Assembly, it will be worthwhile to look at the definition of OEMs and see what they stand for and the kind of offerings they make.

OEM is an acronym for Original Equipment Manufacturer and is a company, which manufactures products, which are, in turn, used as components in the products of another company, which sells the finished goods to the final consumer. In case of electronic devices, an OEM undertakes contract manufacturing of components. This allows the other printed circuit board manufacturing company to focus on its core capabilities and processes. The OEM PCB manufacturer, therefore, has the right capabilities and expertise in creating cutting-edge PCBs that are ahead of the curve. In fact, equipped with industry insights the OEM PCB manufacturer ensures that the final product lives up to its reputation and that costly mistakes that can cost the company its reputation, are avoided.

By using the services of the OEM, the PCB manufacturing company ensures that they do not have to incur increased cost or increase capacity in areas that aren’t their forte.

What are some of the tips for OEM PCB manufacturers can bring to the table?

The one way the PCB manufacturing process can be improved is through PCB Penalization. Simply put, PCB penalization is the art of organizing multiple boards on a single panel. This not only makes production faster, but also more cost-effective. However, to reap the advantages of penalization, here are some tips and tricks that are to be followed. Sample some of these below:

It is imperative to make use of fiducial markers to ensure that the position of the objects is accurate. Some of the rules that are followed for fiducial markers include:

  • The copper pad should be 1 to 2 mm in diameter.
  • The fiducial is made in the copper layer to ensure accuracy
  • There is ample space between the pad and vias.
  • Copper pads must not be coated with Solder mask or silkscreen
  • It is recommended that 3 fiducial marks be used. 2 marks can also be used as long as they are staggered. Use of 4 marks, however, isn’t recommended.

It is also important to keep depanelling, stress free. As a leading PCB manufacturing company in USA, we ensure that mechanical stress is reduced through the following choices:

  • Breakaway tabs present one of the cheapest though riskier options, when it comes to removing PCBs from the panel.
  • V-engraving is an effective way that involves tracing grooves on the top and bottom sides of the panel. Individual boards can then be removed along the v-groove by applying pressure either by hand or through a fixture. Although it is possible only on rectangular cards, it is a quick method.
  • The process of routing involves using a deplaning router to remove PCBs from the panel. While the risk to break a board is quite low, there still is the fear of sensitive components being damaged.
  • In case the design involves an unconventional shape and has tight tolerances, laser cutting has emerged as a good separation method. In fact, it is known to produce least mechanical stress, although it comes at a high cost.

In order to ensure that manufacturing is seamless, it is best to factor the penalization aspect into the designs. That way, you can create multi-board arrays, which are replete with depanelization clearances within the Gerber file that is sent to the PCB manufacturer.

Although different printed circuit board manufacturers have different limitations related to board size, a thumb rule is to use 18×24 inch panels or if your board is too small, to use 2×2 inch panel. That way you can minimize the amount of wastage from any panel and remain efficient.

Multilayer PCB Manufacturing

When it comes to PCB Manufacturing, particularly multilayer PCB manufacturing, the technology that is currently in place, is in many respects not too efficient. Not only is it time consuming, the biggest issue is that it is not foolproof when it comes to avoiding errors.

The big relief has come in the form of additive manufacturing, where it has become far easier to create complex, multilayer PCBs. This technology allows for creating high-density boards which work well especially given the current trend of miniaturization of electronic products.

Before we look at additive manufacturing in some detail, it will be worthwhile to look at some of the issues being faced when it comes to manufacturing multilayer PCBs vide the traditional methods.

Issues plaguing the traditional multilayer circuit board manufacturing methods:

Time Consuming

First up, the traditional method is time-consuming. This is largely on account of the fact that there isn’t any significant automation. For an industry where turnaround times are a critical source of competitive advantage, no marks for guessing, that this comes with its own set of problems. Especially, if you are dealing with high-density PCBs, the time taken for PCB fabrication, as also its cost shows a substantial increase.

Material Wastage

Traditional PCB fabrication also comes with a significant amount of wastage of material. From a cost standpoint also this results in less than optimal costs.

Use of hazardous material

At a time where stopping environmental degradation is the need of the hour, traditional PCB Fabrication processes use a whole lot of hazardous chemicals that cause significant environmental damage.

What additive manufacturing effectively does, is to mitigate each of the above risks and offer tangible benefits through 3D printing.

Additive manufacturing process for multilayer PCB manufacturing –

An additive manufacturing process that employs 3D printing of PCBs, essentially uses a layer-by-layer printing process to produce multilayer PCBs.

We do have additive manufacturing processes that involve printing from silver or copper nanoparticle inks directly to a FR4 substrate. However, this helps in single layer boards where the subtractive etching process is eliminated. When applied to multilayer circuit boards, there is hardly any time or cost saving as compared to the traditional PCB manufacturing process.

What works well when it comes to multilayer PCBs is the process of 3D printing. All you need are superior inkjet printing systems whereby you can opt for a layer-by-layer deposition process. What is of importance here, is that the insulating substrate can also be printed simultaneously. All you then require by way of PCB Assembly, is to add the surface finishing and component placement. You do not have to undergo the drilling process since you are able to print the substrate with mounting holes.

If you look at this multilayer PCB closely, what it really has are traces and vias in a single dielectric layer. The advantage clearly lies in the fact that you do not undergo the geometric constraints that come in traditional multilayer PCB production.

Little surprise then that additive manufacturing is increasingly being used in both, complex PCB fabrication, as well as in creating multilayer PCB prototypes where speed as well as efficiency, is key. The importance of additive manufacturing is also growing on account of the fact that the need for complex, multilayer PCBs is on the increase.

Not only does it work well from the standpoint of quality, from a business perspective too it has a number of advantages, including but not limited to:

  • Reduced time of production
  • Less material wastage
  • Optimal Costs

That it can cater to low-volume, high-complexity multilayer circuit boards, is an added perk! Additionally, with the reduced time of production, the circuit board prototypes can be immediately tested. This by itself offers a number of benefits. Firstly, your time-to-market can be significantly improved and you can gain a competitive edge. If you are a startup and need a minimum viable product to showcase to investors, once again, the importance of this cannot be overstated.

Little surprise then that a lot of industries are benefitting from this new method of multilayer PCB manufacturing. With the fast turnaround enabled by additive manufacturing and engineering changes being easily accommodated, the importance of 3D printing is only slated to grow when it comes to its use by PCB Manufacturers in USA.

The Most Common Types of Finite Element Analysis for PCB Manufacturing!

By | Date posted: | Last updated: November 6, 2020
PCB Manufacturing

Improvements in the electronics industry are being increasingly led by technological advancements in Printed Circuit Boards. Whether it is providing solutions that are transforming our homes and workplaces or providing miniaturized products that add to the ease of use, the impact is far-reaching.

While the macro trends in the electronics industry have been led by developments such as Internet of Things, small home technology and more, there are a whole lot of other design aspects that electronics engineers also need to focus on. These include areas such as lowering power consumption or dealing with thermal issues, particularly under harsh environmental conditions. With teams working on challenging PCB projects, especially in mission critical areas such as defense, mining and more, delivering a successful product is extremely important. This requires a whole new approach in PCB manufacturing.

When it comes to solving any complex problems, the first thing to do is to break the issue into smaller, addressable parts. This not only takes away the overwhelm that comes with complex issues it also facilitates addressing the smaller issues with measurable metrics. The technique that best defines this approach is Finite Element Analysis, or what is popularly addressed as FEA.

Simply put, Finite Element Analysis involves modeling of systems in a virtual environment so that you can solve structural and performance issues in the real world. What FEA does, therefore, is to allow for separation of the process into smaller subsystems that allow its close evaluation. A practical application of FEA is the tracking of material changes. FEA also finds extensive application in PCB Manufacturing, especially as it helps in material selection. Some of the benefits of FEA include:

  • Improvement of product performance
  • Evaluation of different designs
  • Optimization of designs and reduction in material usage

PCB Manufacturing FEA Analysis

There are a host of ways in which FEA Analysis can add value to PCB Manufacturing; be it the selection of components or performance of circuits. The use of PCB FEA Analysis, therefore, adds value at various stages of the process of building boards. Below is a detailed analysis of the various types of FEA analysis that come in handy, during the design stage:

Signal and Power Integrity Analysis

It is imperative for the PCBA to function seamlessly as per set benchmarks, to ensure reliability of the product. It is largely the Signal and Power Integrity of the board that determines this. This in turn involves ensuring of aspects such as:

  • Maximizing SNR
  • Components should have ample power
  • Noise reduction on power traces

Electromagnetic Compatibility and Integrity

EMI or noise can often be a concern with boards, especially if they have RF devices. While try and as you may, complete elimination of noise isn’t a possibility. What is possible, however, is that you achieve the best EM balance for the environment. In systems where there are multiple PCBAS, achieving electromagnetic compatibility is also an important design aspect.

Thermal Analysis

Thermal analysis is a Finite Element analysis that finds wide application in PCB. Essentially, it involves evaluation of the response of the board to different thermal conditions. Whether it is heat distribution on account of the power components or environmental changes, it helps determine the use of thermal pads, vias or the overall design of a thermal management system.

Other than the above, FEA Analysis also comes in handy by component manufacturers as also by testing organizations. Some of the tools required for the same include:

PSpice

This is a preferred industry tool when it comes to evaluate signal responses. With the help of this tool, you can model a wide variety of:

  • Electronic components
  • Circuits
  • Boards and more

3D Solver Clarity

This comes in handy to offer a 3D perspective and analyze the EM parameters

Celsius Thermal Solver

It provides results that ensure there isn’t excess heat that can not only damage components but also threaten user safety.

Armed with these tools you can rest assured that the integrity of the PCB has been checked and reliability of the product is assured. The partitioning approach of Finite Element Analysis ensures that precise evaluation of the different aspects is done and standards adhered to.
