Camptech’s PCB Assembly Process

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.

Customers are informed right away if we encounter any issues or have any queries.

Parts price and delivery are the primary factors that our purchasing department considers when purchasing parts. And, we only buy components from reputable vendors such as Digikey, Newark, etc.

The final outcome of the purchasing process is to compile the required parts to build an assembly kit, which allows production to start.


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.
For instance, if the PCB will be put inside a slot in a cellphone, the board will be tested within a simulation of that slot.

So, functional test is where the assembly is powered up and checked to determine whether it functions according to specifications.


11. Conformal Coating

Functional circuit boards are then washed and dried before undergoing this step of the manufacturing process (if required by the customer).
The boards are either dipped or sprayed in conformal coating – 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.
