Understanding PCB Manufacturing: Silk-Screening

Posted by Paul Jackson on Fri, Sep 06, 2013 @ 02:10 PM

One of the more artistic processes in a PCB manufacturing facility is the application of Ident layers, also known as silk-screening.

Silkscreen is normally used on the component side to identify components, test points, PCB and PCBA part numbers, warning symbols, company logos and manufacturer marks. It isn’t uncommon to have silkscreen required for the solder side as well but if you are price sensitive, you need to know the work required to produce two silk-screens is simply twice as much as one.

Silk-screening requires specially formulated inks. Standard colours are Black, white and .yellow. Non-standard colours can be requested but will impact your cost and your lead-time.

Why Omni Circuit Boards Were 1st to Produce an Aluminum Trace PCB

Posted by Paul Jackson on Tue, Jul 30, 2013 @ 06:03 AM

Today's computing technology is rapidly outpacing the capabilities of standard, mass-produced printed circuit boards. That's why it was no surprise when the engineers at British Columbia based D-Wave Systems came to us looking for a unique product.

Understanding PCB Manufacturing: Electrical Testing

Posted by Paul Jackson on Thu, May 23, 2013 @ 09:22 AM

PCB manufacturing facilities routinely perform Electrical Testing with “Flying Probe” testers which are well suited to smaller production runs.

For short runs, the flexibility of quick set-up ensures cost effective Flying Probe tests outperform the lead-time, cost and fixed designs of dedicated test beds. With Flying Probe tests, no fixtures need to be prepared, only data files. Flying Probe tests are able to reveal not only shorts and opens produced by the manufacturing process but have also been known to expose design errors.

Understanding PCB Manufacturing: Multilayer Assembly

Posted by Paul Jackson on Thu, May 09, 2013 @ 11:28 AM

One of the more interesting activities routinely associated with PCB manufacturing is the process of assembling multilayer circuit boards.

At any given time 40% of our PCB manufacturing at Omni is producing multilayer circuit boards, so understanding the process is important. Layers of copper foil, prepreg and core material are sandwiched together under high temperature and pressure to produce multilayer assemblies. Pressure is needed to squeeze out air while heat is required to melt and cure the thermosetting “prepreg” adhesive which holds the multilayer PCB together.

Understanding PCB Manufacturing: CNC Drilling

Posted by Paul Jackson on Thu, Mar 21, 2013 @ 09:49 AM

One of the key processes in a PCB manufacturing facility is the CNC Drilling Department. Holes are drilled in PCBs for customer requirements: component mounting and to promote conductivity between Cu layers (vias). And for manufacturing requirements: to ensure precise registration and to help the operator ensure each drill has successfully completed the tool path.

4 Tips for Saving on Circuit Board Prototyping Costs

Posted by Paul Jackson on Thu, Jul 19, 2012 @ 01:04 PM

1) Thermal and antipad clearances

Considering thermals and antipad clearances on the power &/or ground plane layers of multilayer boards - if layer to layer registration, tolerances for hole size, location, film expansion and registration have not been taken into account then manufacturing will experience high reject rates and increased costs.
