You also need to consider the total metal load in your dispensable paste. You'll need a slightly higher flux content and less metal, say around 87% total metal, in a 4 or 5 mesh size. We had to have some special mixes made in order to do fine pitch

Hi Danny, Are you doing lead free? If yes, I would consider the AE-R330A or SMT-2010 lead free reflow oven. Our reflow oven is affordable and brand new. Just want to make sure what size is your board. Also, all of our equipment comes with one year s

Has anyone had issues with Renco inductors failing. The component I'm having problems with is a 330uH shielded power inductor. Out of 36 board failures, I have 17 that failed because this inductor failed. Most often they end up reading -1.34 uH.

We currently have a project requiring us to place multiple QFN devices (of various sizes). The pick an place is not a problem at all, where we are seeing 'problems' is that 3 of the devices are being place on locations where the ground pad have plugg

Just been quoted GBP500 for 5kg (2.7L) of Galden LS-230. Don;t know if the lower temp non-leadfree stuff is cheaper If anyone in the UK has a small qty they'd sell me for experimentation, (e.g. old non-leadfree stuff they no longer use) please get in
