Electronic circuit assembly

Electronics are all around us, from home appliances to communication and transport. At the core of electronics are printed circuit boards, also known as PCB. These characteristic green circuit boards possess no functionality until the correct electronic components are mounted on them. MyProto’s domain of expertise is the assembly process, where the correct electronic components are mounted on the PCB.

Our area of expertise

At myProto, we provide both the necessary skills as well as high-end machinery to assemble functional electronic circuit boards. We also perform a PCB file check, along with our PCB partners, on the design data in order to identify and correct any potential errors before the manufacturing process begins. That way, we cut down manufacturing costs and eliminate unforeseen expenses.

 

 

How we work

Our electronic circuit board assembly process consists of seven phases, combining automated and manual assembly.

 

Solder paste stenciling

During the first phase, small apertures in the stencil will allow the solder paste to be carefully and precisely applied on the targeted areas. The machine then spreads the paste evenly across the stencil.

 

Pick and place

The boards now move to our pick-and-place machine. The machine attaches all surface mount components (SMD) to the board, eliminating any potential errors that could appear with manual mounting.

 

Reflow soldering/ solder solidification

At this point, the boards move through a large reflow oven, heated to around 360° degrees. This will cause the solder to melt. Afterwards, the board is gradually cooled in order to properly allow the solder to harden, after which the SMDs are permanently and properly connected to the PCB.

 

Quality control

After the previous three steps, which have been mostly automated, it is time to perform a quality control and check for potential errors. We implement manual checks, automatic optical inspection and x-ray inspection, depending on the volume and specifications. This quality check is followed by a test of the electronic circuit board connections.

 

Through-hole mounting & soldering

Depending on the design data, boards may include through-hole (PTH) components, which are different from the usual SMDs. Mounting such PTH components requires specialized techniques such as manual soldering or wave soldering. Such methods are implemented during this phase.

 

Final inspection

Final inspection is done on every single board based on the applicable IPC standards. We verify correspondence to validated component orientation, solder quality,
component placement accuracy, cleanliness, as well as correct and complete production process prior to shipping. Finally, a summary is sent to the customer in the production report.

 

Packaging

Every single board is packed in an anti-static shielding bag and then placed into a box, well stuffed with anti-static foam. This way the pieces are protected against static discharge and eventual rough handling during transport.
