We are changing over to a No-Clean paste soon and l was wondering how other people tackle the issue of stencil and PCB cleaning in high-volume production. The paste we are using is Cobar 325RX and its pretty sticky stuff let me tell you! Our proble

Reflow profiling/soldering is a process in which a solder paste (a sticky mixture of powdered solder and flux) is used to temporarily attach one or several electrical components to their contact pads, after which the entire assembly is subjected to c

SSD can be used on both sides of the pcb. Although , it is not very logical to use it on the bottom side of a pcb that has numrerous Through-hole components, that are to be wave soldered. There are many advantages to SSD. The amount of solder is much

You can't really use a pasted board to troubleshoot the program as any components not on target simply slide off with machine vibration and movement as they won't be held by the solder paste. Whereas on double sided sticky tape they remain in place
