ASPIS (Advanced Surface Protection for Improved Reliability PCB Systems) The three year Aspis ‘Research for SMEs’ project has been conducted to address problems found with the nickel gold (ENIG) solderable finishes that are used by the electronics in

Hi Leadthree, We have a combination of methods depending on volume, value, size, level of build, and what the customer does with them. So on high volume low value we have rigid plastic ESD boxes with lids, foam lined, that layers of custom vac form

You can buy an awful lot of PCB's with that budget. Having done multilayer at home for RF I would not recommend it. It took us 7 years to get a workable but I would not say reliable process running. 4 layer boards, plated through, green and silk scr

It's nice to be able to do things in house, and it's good to have somewhere without commercial pressures to learn and make mistakes, so I can understand where you are trying to go. Those machines look a little lightweight for consistent quality pr

Someone with some more definitive knowledge of these machines will no doubt chime in at some point, but my thought was that the "A-table" is just a data table that stores I/O information. Thus, being "off in A-table YV100X:N2323 YV100XT:n2223" just m

Contact George Castonguay at PPM. He is a Jedi when it comes to these machines. In fact, since you just got it, a good investment would be to have George come in and go through the machine and get it calibrated. 603-895-5112 They also sell parts

I want to avoid peoples preferences as they will differ and will not be a deciding factor. A heat gun will introduce risk to surrounding PTH components and having to add protection for those, will limit any gain in productivity. There is no question

We have recently received some pre-tinned "flat lead packages" and the question I have relates to the definition of solder touching the component body of the part. Typically when I have gold lead parts tinned there is a gold gap between the tinned po

Buy flex rigid boards from a board shop. Seriously I think the time is at the original fabrication of the board. AFAIK, they use sheets of FR4 bond the parts that will remain to the flex and cut away the rest. It would not surprise me if they use a

Perhaps google this, as you will find very interesting articles. For scientific explanation look up solder fatigue on Wikipedia with references added. A more in depth explanation you can find on the Digikey forum where you will find other people like
