Chip reflow
WebThere is a video on YouTube explaining how to reflow the southbridge chip in order to get the system to work and I tried just that. I used Alseye S420 thermal paste, BAKU flux gel, Ronix 1104 heat gun at 450 degrees celsius and 95° ethanol. Truth be told I may have added too much flux around the chips which resulted in me using LOTS of ethanol ...

WebOther users confirmed that the wifi chip could be responsible for preventing the Switch from booting. I think that maybe the solder connections are actually the problem, and not necessarily the chip itself, as many users have reported the problem to be intermittent. So a reflow, reball, or worst-case a replacement, of the chip should fix the issue. WebReflow soldering is the most widely used method of attaching surface mount components to printed circuit boards (PCBs). The aim of the process is to form acceptable solder joints by first pre-heating the …
