A lot of our PCB's are being damaged by our water cleaner, it is a Steolting Triton, and I beleive it is due to the drying section in the machine. The air its blowing on the boards is flipping the boards around on the conveyor and smashing small deli

Yes it happens with any inline cleaner with small or light boards the pressure can cause them to flip. If they lodge in the links they can also cause damage to the conveyor. For small boards, flexibles etc you do need a mesh fixture of some sort or l

The only people that can answer what you need is UL. I worked with VDE and I do not know any company that works like that. With VDE we prepare a module according to VDE standard and do an internal pre-approval - and present it. To put something ra

We're having problems with Kester pastes (NP545 pb free and EP265 60/40 no clean pastes.) All of our other components reflow just fine with either paste, but for some reason this QFN chip doesn't wick to the QFN's pads well. It seems like some type

I prefer simple sequential P/N system. We use digits 0-9 and english aplhabet (total of 34 characters). Letters I and O are ommited to avoid mix-up with digits 1 and 0. P/N is 6 characters long - long enough to cover ~1.5 billion parts but short eno

I do not see anything obvious that would cause a thermal mis match. Regarding reflow profiles reducing tombstoning, Unless there is something wrong with your paste or you are running smaller than 0402's, I have NEVER seen a reflow profile reduce tom

We often do double sided SMT assembly, never had issues with smaller components. However, we apply glue to heavier components like inductors, SD card sockets etc. For this purpose, we have a glue dispensing machine inline after the solder paste prin
