PCB Assembly
Printed circuit board assembly is the complete board with all the soldered & installed components. We use surface mount (SMT), through hole and mixed technology to manufacture consigned printed circuit board assembly, turnkeys, board types with metal cores, etc. as per requirements. Our PCB assembly services range from prototypes to large production orders.
We cater to the tailored requirements of our clients whether their needs are a quick turnaround prototype or mass production with our prospered craftsmanship.
We provide a broad product mix from manufacturing sky-scaping count, back panels to layout including blind, micro, and buried vias.
As a leading printed circuit board assembly manufacturer in California, USA, we use advanced technology to take control of the plenary process. We maintain in-house PCB assembly manufacturing services to provide complete PCB solutions. Our PCB manufacturing and assembly process follows international quality standards. PCB assemblies are the core of any electronic devices. Following are some of the benefits of PCB assemblies:

Benefits of PCB Assemblies
Compact Size
Copper tracks are more used in PCB than wires, making inside connections less heavy. Although the size of PCB assembly depends on the request from client.
Save Time
Our PCB assembly process from procuring components, materials, production coordination, inspection between process and final testing will result in saving overall time.
Cost Effective
We provide in-house testing or inspection for any kind of requirements of PCB assembly which allows customers to save the cost of separately testing PCBs somewhere else and ensuring quality. This is cost-effective in mass production PCB assembly requirements.
Low Noise
This improves reliability in devices as heat overcomes electrical noise.
PCB Assembly Services
- Single-sided PCBs – These are the simplest type of PCBs which are used in simple systems. They contain only one layer of base material. Copper is used to cover that layer. The solder mask protects the copper layer.
- Double-sided PCBs – These contain layers on both sides. Double sides are used to attach the metal areas. Surface mounting is more efficient than Through-hole mounting to attach more circuits.
- Multi-layer PCBs – They have many copper layers but not less than two like 4 layers, 6 layers, and up to 12 layers. Circuit boards are compact. These are more flexible as they provide sufficient weight and space.
- Rigid PCBs – These bases consist of hard solid materials, and the signal paths are well arranged. They are inflexible. Mainly used in the motherboard, aerospace, etc.
- Flexible PCBs – These bases are made up of flexible materials. They reduce complexities and circuit board weight. They require less space. The correct temperature and density are required due to the flexible nature of circuit boards.
- Rigid-flex PCBs – These are the combination of Rigid and Flexible PCBs. They consist of many layers of flexible circuits that are connected to the rigid boards. They are light weighted.
PCB Assembly Process and Technology
The entire process and functions are done by several processes, as mentioned below:
THT (Through-hole technology) assembly process
In this process, holes are made into PCBs. Then, pin-through-hole components are inserted into it. These can be done by soldering.
These include the following steps:
Step 1 – Placements of components
Check the client's circuit board design documents and accordingly organize and fix all the components.
Step 2 – Checking and rectification
After step 1, plug boards and components together. In case of any issues, it will be fixed by soldering method.
Step 3 – Soldering
Wave soldering is done at a high temperature and by moving the circuit boards in the liquid solder via waving.
SMT (Surface-mount technology) assembly process
Using solder paste, components are placed in circuit boards.
The following steps are needed in SMT:
Step 1- Printing
A solder paste printer is required to solder paste on components and boards. Use stencil to ensure it is done properly or not.
Step 2 – Mounting
After the solder paste printing, the PCBs are sent to the pick and place machine automatically for mounting components and integrated circuits on the pads with the solder paste effect. After that, the component reels are required for the installation of components onto the PCB boards.
Step 3 – Soldering
Reflow soldering is done at high temperatures. Circuit boards are placed in an approx. 22-foot long furnace.
Mixed Technology assembly process
Single side mixed
All these procedures like printing using solder paste, placement of SMD parts, reflow soldering, wave soldering, and placement via through hole technology are necessary to do.
Among the two sides, SMT One is THT
For the best results, there are a few procedures that must be followed like surface mount adhesive, SMD parts placement, flipping, solidification, wave soldering, and PTH placement.
Double side mixed
Surface mount adhesive is the optional step.
In the double-sided mixed PCB assembly, it is processed in both ways with or without adhesive. Surface mount adhesive is an optional step based on requirement. All other steps of single side and between the two sides are used.
