PCB Assembly Process Advice

An inherent understanding of the equipment and processes utilised in the population and assembly of your boards is fundamentally important to specifying a board correctly.

Every OEM or EMS customer have a standard set of specifications that the boards need to comply with to be able to manufacture the PCBs correctly and in the best way to achieve a high manufacturing yield. We store these specifications and apply the requirements to every order as part of our DRCs (design rule checks).

Our factories offer the full range of solderable finishes and solder resist options that can be matched to your assembly process and peak process temperatures. We can always recommend the best-suited finish relative to the board details and process, but even special requirements can be catered for, including special processes that aid manufacture and product performance.

For example, if a matte finish resist works better for your pick-and-place and AOI cameras, we can ensure that this finish is used on all of your boards. Selecting appropriate solder resists, idents and peelable resists for multi-stage assembly is also part of the service we provide.

We do not just simply match a given specification as this adds little value. We try and guide our customers towards aspects of PCB specification that fit ideally with your particular assembly process.
