Small paste deposits have less flux thus less flux activity to enhance the wetting. So preheat needs to be as short as possible, ramp to spike if possible. Try not to ramp hold and spike - pending thermal delta on product can be made to ramp to spike

Hi, I have faced some problems with DQFN PACKAGE 132 PIN. After some cross sections and dye pry analysis we could find a head on pillow situation always on inner row pads. The PCBAs are double side and the DQFNs are assembled on Bottom side (Noteboo

Hello to everybody. Does someone have some experience or review in the past with roller tinning machines? I mean low cost machines with two rollers and a molten solder tank. The finished soldermasked PCB pass through the rollers (like a lamination)
