Yes, it is possible, and yes you do need to watch out for preheat and soldertime. The displays will get the hottest after they leave the wave, when the heat creaps from the PCB to display. Check your datasheets and do some testing for maximum heat.

Hi all, Assuming that i were to design a PCB and there are multiple components, what is the minimum spacing required to ensure that i won't have problems in my SMT process later on? Also, is there a minimum component stand-off height spec as well?

For your pad layout and spacing between components, look here: http://portal.ipc.org/Purchase/ProductDetail.aspx?Product_code=77b562c1-b8f8-db11-8a6a-005056875b22 For your standoff height in SMT, we do not concern ourselves with standoff height. It

So next time that you order boards from your fabricator, consider asking the your fab to cap these pesky via on the solder side with SR1000 [or whatever they think will be good and cheap]. Think of the money you'll save. Your boss will be ecstatic!!!

Continuing with the idea of capping the via with SR1000: If you have boards in-stock that will require all the putzing around that you've doing to prevent the solder flowing through the via, consider reworking your stock with SR1000 to prevent all th

Just to update. I tried using the temporary solder mask again and it worked great. I guess the first time I did not let the mask to cure long enough. Also, I inquired about have the via's plugged with SR1000 in the future and I was told by our PCB

I tried using camtastic! but i don't see a "tool menu" or "assembly utilities" in any of the menus at the top. I did a search on the help and it doesn't guide me to how to access this function. If you can help me it would be much appreicated. thank
