Hi All, We are gathering information on the environmental conditions in our facility, including the fresh air exchanges. A driving factor is any point of exhaust that goes to the outside air and the CFM that it pulls from the facility and if there

Where you inspect depends on what you're looking for. X-Ray is a fairly specialized piece of gear and doesn't lend itself for example to paste registration or thickness measurement. A laser system is better suited. An X-Ray system would allow you to

TK, Hope you got it right only for this round of assemblies. Well, passing through a Reflow belt is not an ultimate process to dry circuit cards & take out moisture from Solder finished layers. First of all, if the packs were not unsealed (even s

We are building a plasma diagnostic to monitor MHD phenomena in tokamak. As part of the development, we need high-voltage, high-power RF capacitors to tune and match an inductive load. This application is similar to a small induction heater, with t

Hi I do not work for a board house but a manufacturing facility where we do a considerable amount of soldering wires to through holes. We pretin our through holes on both sides of the PCB prior to reflowing the solder and installing the conductor (w

We have been using a selective solder system for all of our automated LF through hole processing to this point. It has served us well but volumes are increasing and we are getting ready to pull the trigger on a full size wave machine to handle the l

I have fabricated a artwork of stencil on a mylar and make comparison on PCB and Stencil in order to confirm if there is any PCB stretching at both end. The results are comparable for both stencil and PCB without any stretching . So,I assumed that th

Yes Aegis and Valor are good choices in terms of NPI, SMT programming , which one you choose will depend on other factors, Valor offers I feel a more rounded product, ie under one platform. Both offer CAD-BOM to SMT and Documentation, but Valor offer

We have inline reworkers, so this time has been factored in. We currently use Siemens S25/20 machines with M1 systems. The placement machines run a little slower than the AOI at times so there is time to perform review, most of the time. It's not
