PCB Assembly

ISO 9001:2015 | ISO 13485:2016 | AS9100 Rev. D Certified | IPC-A-610 CLASS 1-2-3 | J Std 001E Class I, II, and III

Printed circuit board assembly is the complete board with all the soldered and installed electronic components including resistors, diodes, transistors, etc. We use surface mount, through hole, and mixed technology to serve full turnkey and consigned PCB assemblies, board types with metal cores, electromechanical assemblies, box build assemblies, and more as per custom requirements. It ranges from prototype quantities to large production orders.

We provide a broad product mix from manufacturing sky-scaping count, back panels to layout including blind, micro, and buried vias.

As a leading PCB assembly manufacturer in California, USA, we use advanced technology and follow international quality standards to take control of the plenary process and maintain complete PCB solution in-house.

PCB Assembly Process and Technology

THT (Through-hole technology) assembly process

In this process, holes are made into PCBs. Pin-through-hole components are inserted into it by soldering.

These include the following steps:

Step 1 : Check the client's circuit board design documents and accordingly organize and fix all the components.

Step 2 : Checking and rectification. Plug boards and components together.

Step 3 : Wave soldering is done at a high temperature and by moving the circuit boards in the liquid solder via waving.

Through Hole Assembly

SMT (Surface-mount technology) assembly process

Using solder paste, components are placed in circuit boards.

The following steps are needed in SMT:

Step 1 : 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 : 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 : Reflow soldering is done at high temperatures. Circuit boards are placed in an approx. 22-foot-long furnace.

SMT PCB Assembly

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.

Blend of SMT and 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

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.
