Dear all, we are using the lead-free SN100C solder alloy for wave soldering. We are experiencing wetting problems each time we have to solder a thick board or a board with a large ground plane.I think that maybe we are not using the right flux. I w

I'd say it all depends on the CM, and how they cost out their production floor. I've seen everything from a flat cost per component placement (something like .05/machine placed smt part, .15/machine placed tht part, .25/hand placed tht part) to stra

We know nothing of DeFelsko, but do understand how they distinguish between the solder mask and the conformal coat. DeFelsko manufactures hand-held, non-destructive coating thickness gages that are ideal for measuring the dry film thickness of confo

Our board layout folks are currently designing a PWB using a 132 QFN. The component is .5mm pitch with .35mm square pads. The component manufacturer recommends the following footprint: .4mm square land .3mm square solder resist 1.why do they spec

I was wondering if there is anyone out there who is soldering the Luxeon Lumiled LEDs into product. We are working on a product that uses them. They are a challenge in that the are SMT parts, but will not withstand reflow temperatures. The manufact

Of course there are differences, different equipment, software, tools, etc... We just got a set of questions from a PCB house asking about soldermask clearance between 16 mil pitch pads. Our current manufacturer can put down 3 mils of soldermask.

Depending on my customers needs there are functional test requirements for PCA's and mechanical assemblies. Soem of my customers have developed and provided dedicated functional test beds. Others are not to sophisticated and expect the unit to power

DBA tried to re-write thier software at least twice and failed. They ended up buying/partnering with EZ-Jobz from I think Austrailia. The new product and the old product are not the same at all in any way. Manex was originally based on FoxPro. We are

Aegis always told me that they wouldnt go into the full MRP thing believing that this was not their core speciality even though it would make sense but last I heard was that they were talking to Manex about making the two systems interact - this was

Origin is New Zealand I believe - which means it has been regionalised to the US and I want it put back to British. "Old" DBA seems to have been put out to grass so I am ignoring that one. My present MRP is FoxPro based - and is being rewritten in
