Hi there, kindly help to advice me either epoxy/glue at bottom SMT component such as chip package 2012 will cause the component to be non-wetting after run reflow process?

Hi Loco, my PCBA got top side and bottom side and 90% SMT and 10% THP (top side) which need to be cover by wave solder. And that's why i need to go through reflow and wave.

solder the part is for SMT component (located at top side and bottom side) and wave solder is for THP (located at top side only).

How many mils the gap between the terminal and pad? Your practice is for technology SMT-4? What is problem with glue cure? is it due to the reflow profile? how long the glue can be keep in room temperature with humidity 40-60?

Shy You should try SMT-5. First solder PTH comps, then apply paste with your pick and place and apply glue with ur screen printer and come back to place smd with pick and place and then reflow. You will get great results. Good luck

Hi Habsfan, if we're mount the THP first, we can't run SMT due to tTHP is tall and big which will causing the PNP to be chaos. Btw, my solder paste location is more than glue location which (solder paste : glue) is 2:1.

Hi Loco, If i cover all the SMT component with peel off before reflow, it'll increasing downtime at my production site. To reduce the downtime, we had idea to add in the glue for component package 0805 and bigger.

Does anyone know if there is a SMT socket for a 1206 cap, I swear I used them in the past but can not find now. If you know of one could you provide a supplier name or web address. Thanks
