THE OPTIMIZATION OF THE SOLDERING PROCESS THROUGH
WebSolder shorts are common on SOIC devices. If the short is in the middle of the row and the pad width is below 0.022", it is a process problem. Fluxing is the first area to examine, then look at adjustment to the contact time in the wave. Often changing the angle of the conveyor eliminates this defect. Unfortunately many wave soldering systems ... WebIf selective soldering, then a "jet" tip, increased dwell time, and longer preheat should help. We selective solder as much as we can and have good success with it. ... as the top side of the board has to be protected from the solder coming over the thickness of the board and allowing solder to short everything on the top side of the board ... top rated sleeper sofas 2015

WebOct 6, 2014 · Reaction score. 5. Trophy points. 3. Activity points. 167. I am exploring the possibility of wave soldering small SMD like SOT363/SOT563. Currently we do reflow on such small footprint components. All the small components will be leaded pins, so from my point-of-view, are "suitable" for wave soldering. WebJul 31, 2024 · Some best practices in selective solder pallet design include proper PCB orientation in the selective wave pallet. It is recommended to angle the board between 15 … WebApr 15, 2024 · On these oxide threads solder will adhere. If such threads are bridging between pattern parts a short circuit is formed. Webbing is caused by an interaction between the solder resist and the solder oxides on the wave. Normally these oxides from the wave surface are reduced by the flux that is applied on the board. top rated sleep tracking devices
