I use Trace Labs and certainly recommend them. I actually just had this test done last week. Adhesion test per ASTM-3359 Method B. We also use Humiseal 1B73, which is similar to the 1B31 you use. Is your soldermask "active" enough for this coat

Our Panasonic KME Create CM95R-M pick and place machine was in storage for a long time and the system battery died, so now the static RAM is corrupted. We need to obtain a "key" floppy to reflash the static RAM. Thank you in advance for any advice an

We are having a lot of tomb stoning with this no clean solder paste. It's limited to larger, complex boards, affecting 0603 ferrite beads, capacitors and SOT23s. It was suggested that paste removed from a stencil should not be put back in it's origin

In my experience Both Dek and speeline machines are good used. personally I think speedline seem to hold up better when PMs have been ignored though. Also make sure you can get a third party board support system into it like a gridlock or Vacunest

Okay, that was weird :| I didn't see the forest because of trees! Anyway, that's a step forward though I saw that OrCAD exports in .txt file and not Excel, as I need. Any ways to work around? Again, please be patient with me if, again, I can't see it

In those cases where we have a 3.2mm thick, 16-layer board with several GND layers, do we still need ground connection to each and every layer (with thermal relief) or, skip part of the ground patterns? Will it help soldeing rising. I can't reach mor
