Could you make up your own adaptor cable to connect to your programmer, then fit a small form connector like a Firewire on the edge of the PCB? It should only take up about 7x7mm of real estate as opposed to a 2.54mm 5x2 pin header 12.7 x 5.08, or a

You can achieve a wide range of dot heights when stencil printing by using a polyimide stencil along with a .040 snapoff. Loctite has a system for this that they call Varidot, by varying the size of the apertures in combination with the .040 snapoff

It will be tough to find a dimensional thickness specification for HASL. IPC-6012 Table 3-2, line "Fused tin-lead or solder coat - Coverage and Solderable" states the requirement that there has to be complete coverage of solder on the land, and it mu

Most white papers, like this one http://members.ipc.org/ipclogin/ipcmembers/IPC/Route/0706/0706techpaper.pdf, have written that lead contamination in a lead-free solder joint leads to all sorts of reliability problems. Consensus is that, if the cont

"For the lead free soldering of electronic assemblies, the inclusion of silver in the alloy results in better wetting compared to non-silver containing alloys and also allows for a broader process window. Silver also improves joint reliab

Off hand, I can't recall a "formula" for how long boards could sit in a specific RH environment. I've done a couple of quick Google searches, and can find a bunch of information on the dispersion rate of moisture in various PCB materials, but, nothi
