Hi BR, Are you screen printing adhesive to the bottom of the board? If so, have your stencil make put openings between the leads of the thru-hole part. SMT adhesive acts as a natural solder resist. So placing a small sliver between the pads works

Hi Pete, we use and have been using Brady Lasertab markers, they hold up through oven and wash, we use a standard laser printer (I believe we use a special toner though) and a software package called labels unlimited (can find on ebay or amazon) whic

Is there any way to generate a printable (ASCII text)component info file? We don't have LAN capability on this machine, nor do we use PPS, and I can not for the life of me figure out how to print something to help the operator set it up. Worst case i

I think you can reach that screen with SH SET command, then do a SET [command name] [value] to change it. Make sure you write down the original values somewhere or do a print screen of your current settings before tweaking them, though.

Why look at buying expensive equipement when you can have your board house multi-up a panel of boards for you. You just saved at least $150,000 American, didn't have to re-evaluate any solder paste, and even opened your process window on your oven.

In the marketing description of your paste, look for "percent metal by volume." This percent metal by volume figure gives you a good approximation of the amount of metal in each solder paste brick that you print on your board. In most solder paste fo
