we have a variety of products which we build and manufacture and build on our site, 90% of which go over the wave solder. What I would like to know is when designing a WSC how do I know what the correct angle of the aperture is in relation to the wav

Yes, sure. In fact in some applications ICT is coming back. Mainly due to the fact that more and more SMT discrete components have no markings, so AOI cannot tell you if you have the correct value on the PCB. Fixed pin or flying probe ICT is a valuab

| I have a recent design (1 component side only) that calls for 2 surface mounted antenna's (brass plated) to be mounted on a PCB. The problem arises when the PCB is 18x11.25 and has 15 to 20 PCB's in the pallet (IE weight, fixturing to hold the ant

Hey Kyle - Good for you for pushing your horizons and considering pin-in-paste (aka "Intrusive Soldering"). Don't let the nay-sayers out there discourage you. When I encounter mixed tech PCBAs (SMT and through-hole) my first choice, if the design a

Have experienced this on a few different cap. parts. Agree with other postings. Following are solutions to problems we have had: 1) Cracked cap too close to board edge per IPC spec. Designer replaced part with 3 caps in series to eleviate stress

What is the shift structure of your shop? If your facility has only one 8 or 9 hour shift per day, then a 3-day turnaround is nearly impossible. However, if you are running multiple shifts that keep the shop alive 24 hours per day, then it is absolut

My first reaction would be to run! FAST! Flex -- well, it... flexes... and isn't flat. While you assemble it, While you transport it, While it goes through the oven... SMT Connectors typically need to be held down during reflow. Fiducial types are

Q1.� is it mondatory to test all components and paths in the PCBA; and check all soldering joints? A1. Nothing is mandatory. You do ICT to prove some component functionality and check manufacturing process. ICT test coverage is driven by factors i
