We are looking into using Scored PWB's on a new high volume design. We've used Tab Routed PWB's exclusively in the past. I understand that Scored PWB's are more efficient to produce and depanelize. Question: What are the industry standards for cr

I received a request from customer to assemble ceramic substrate (alumina oxide)that printed with a low temperature Copper thick film conductor (the overglaze layer is polymer). The Copper pads are exposed without any coating. This ceramic substrate

Smells a lot worse even with good extraction. Key things to look out for is laser life on your thickness and layup of panels compared to spindle motor life (Typically 10,000 hours, or 2 years for us) and cost of replacement lasers. We get spindle

Hi Clarissa, seems to be a real start up situation you are in. For the printing there is IMO no need to buy any sophisticated automatic-vision-alignment-self-cleaning-inline-and-more-machine. Features you need: - adjustable in X-,Y-,Z-axis (individu

Adrian, I'll go again. The term "snap off" on it's own refers to the distance between the bottom of the stencil and the top of the pcb. Sometimes referred to as "print gap". As you prefaced your question with "squeegee snap off" I thought you were as

Sounds like someone aimin� fo tha big hurt, if ya axes me. Two spots to place your lawn darts are: 1 J Hwang in "Modern Solder Technology � " states (p.354) that " � extreme CTE mismatch between silicon IC (~2) and the PCB (~16), solder connections

Doug, We've suffered through similar frustrations. One thing we found that might be of some help is uur supplier, unbeknownst to us, was outsourcing their immersion gold. Their supplier apparently lost control of their process for a period of a fe
