Guys, Unfortunately breakaways aren't an option - they are large boards and we already have problems hand placing components and probing them. The ridges - yes we can remove a few - and that solves one problem (boards bashing together and damaging

Quick question for anyone - With this whole pasting and waiting thing - i've found out that the board is pasted, it sits around for a bit, then the components get placed on it. Then i thought it went into the oven BUT, it doesn't. It sits for a few

Yes, Hand Up here. I would think you would have a quality problem. I am assuming you're doing this process in some sort of batch mode. I would hope that you can process your boards within a few minutes after components being placed. Things that I

We have 4 EVS machines in our facility. The operators like them, maintenance doesn't. The PM's aren't that bad it just that maintenance doesn't like doing them. On a few of the earlier machines we have if the operators are not careful they can get mo

We do not recommend array sizes. PCB houses take a single board and turn it into a step/repeat that is best fit for their process = cheaper boards I suppose. We then approve this array and build programs and tooling to match. On occasion, we recei

The first thing that I would do is contact the smock manufacturer and ask them for advice on testing the smocks. ESD FROM A TO Z 2nd ed. (Kolyer) states that: smocks should have a resistivity of less than 10^12/sq and must not shed steel fibers.
