Currently, we are baking any PCB before process on SMT, the 'reason' is to dry any possible humidity that could be inner the PCB, it does not matter if the PCB is multilayer or not. We bake PCB's at 107C for 4 hrs and the board must be process into n

Reflow soldering of 208-RQFP-0.5mm

If I brief shifting, I checked the component before it enter the reflow oven and saw that the IC is perfectly aligned on the pads but when it comes out from the oven the IC is floated on the pads. The floating is irregular and the IC is shifted away

Masking with hight temp non silicone tape before wave

Electronics Forum | Tue Feb 17 15:24:17 EST 2009 | glynnhamer

I know this is going to sound rather sad, but we have been using a Capton tape for years that contains silicone to mask large components as they go over the wave, as well as large plated holes on the pcb. It was handed down for years as accepted prac
