I'd say you build as they ask but you must have written confirmation of what they wish you to do. One thing to remember is that it's not illegal to make non rohs compliant products, it's only illegal to sell them in certain markets, your not to know

Cost will first and foremost be your deciding factor here. Cant go wrong with Electrovert or Soltec. TD has some decent stuff. As far as beoing comaptible, most all mfgrs are now making only pbfree comapatible. it seems to cost about $8 - 12k to

Oh, please, give me a freaking break!!!!! Can't you keep politics out of this forum. Not the Brit. What they use in Turkey and Tunisia- yeah, those two technical hot beds, they know electronics like I know making a carpet. Syria- you should be next f

could be black pad, or it is just bad reflow profile that did not get all balls soldered down. OR it could be a planarity issue between BGA and fab during assembly. Can we assume that this is proven design? Somewtimes in new design touching a BGA

Good afternoon, We use PD955M daily and are also happy with PD955M. Consider PD955�s printable version: PD955 PY or PD955 PR (difference is only in color: red or yellow). Do not use IPA for cleaning. IPA tends to harden adhesive making cleaning extr

The touch down sensor is probably the culprit, however make sure the head is not impacted with old solder paste and that the cylinders that flip the head are functional. I have had problems with one of the cylinders not functioning this caused the he

Q1: What is leadfree soldering? A1: Look here http://www.niccomp.com/NIC_RoHS_WEEE_Update_0305_b.pdf Q2: Why is it preferred over the convention leaded soldering? A2: Eurolanders legislated it without proper investigation into the environmental a

Typical of QE types. They don't know the entire process of qualifying what makes a "good" board (besides FPY), so they just arbitrarily come up with 95% FPY as a benchmark. Russ made a great point that alot of yield issues are design-related. Typi

For reflow, bump up your profile as hot as you can go as allowed by your paste manufacturer will allow. If you can change solder paste without too much red tape, several solder paste manufacturers make a transitional paste designed for mix of lead a
