What is a Printed Circuit Board (PCB) Assembly?
A printed circuit board assembly (PCBA) describes the finished board after all the components have been soldered and installed on a printed circuit board (PCB). The conductive pathways engraved in the laminated copper sheets of PCBs are used within a non-conductive substrate in order to form the assembly. Attaching the electronic components to the PCBs is the concluding action to create a fully operational electronic device.

PCB ASSEMBLY PROCESS
CAMTECH PCB delivers complete PCB Assembly services with advanced manufacturing capabilities to fulfill all of your assembly requirements. From prototype assembly to production quantities, bring us your design and walk away with your assembled boards.
1. Parts Procurement / Kitting
The initial step in processing a customer order is to check all the information and data that we receive from our customers. The accuracy and correctness of the Bill of Material (BOM) are critically important since it is used for purchasing the parts.
2. Solder Paste Printing
Solder paste is applied to the PCB component pads, using a stainless-steel stencil. In this step, precision is key, as the solder paste must be applied in the correct places using correct thickness to ensure full functionality of the joints.
3. 3D Solder Paste Inspection
Due to the complexity of PCB designs containing small components in densely-packed spaces, the inspection stage is a crucial step to ensuring an accurate printing process. Each board is scanned to produce a 3D image, which is reviewed for correct solder paste volume per pad, stains, proper alignment, and the absence of foreign materials that may have adhered to the paste, among others.
4. SMT Programming
The Surface Mount Technology (SMT) machines are programmed with component placement information. Most often, the program is generated using Centroid files, Gerber files, and BOM data.
5. SMD Placement
As the PCBs pass through the SMT machine, components are placed onto the pads to which solder paste has been applied.
6. Reflow Soldering
At this stage, the PCB enters the reflow soldering machine, where it is held under an infra-red heater in order to melt the solder paste. Once the solder paste solidifies, the components adhere to the contact pads, therefore connecting the joints.
7. X-Ray Inspection
After completing the reflow stage, the boards are sent for X-ray inspection, which is an especially useful method for reviewing complex or layered PCBs. The image produced by the X-ray can be analyzed by image processing software to find defects in the joints – including incorrect amounts of solder paste or skewed component placement.
8. Automated Optical Inspection (AOI)
An AOI machine consists of a series of cameras placed at different angles, capturing the placement of the solder connections. Using image processing software, solders of subpar quality are detected based on how light is reflected off of each solder connection.
9. Wave Soldering
In this stage, the boards are placed on a conveyor belt and passed over a tank of molten solder, which is pumped to create “waves.” As the boards pass over the upwelling solder, the components with leads on the bottom side of the board, which come in to contact with the solder get soldered to the PCB at the same time.
10. Functional Test
After all assembly stages have been completed, the PCB as a whole may be tested for overall functionality. The test is conducted through an interface connected to the PCB that simulates the electrical environment in which the board (as an end product) will ultimately be placed.
11. Conformal Coating
The boards are either dipped or sprayed in conformal coating which is a protective layer that guards against deterioration caused by atmospheric moisture, condensation, contamination, and other occurrences that can damage the PCB over time. This step is important for ensuring the longevity of the boards and the productivity of our clients by preventing corrosion, dendric growth, erosion, and short circuits.
12. Final QC
The final step of the manufacturing process is a 100% visual inspection done under a magnifier. Primarily, the board is checked for soldering and joint defects, cleanliness, flux residue.
