A-620G doesn't require 100% wetting to the thermal pad. It requires 100% wetting to the land in the end-joint area. The end joint is the portion of the solder connection that is at the top [or bottom] of the connection. Look at 7.1.3 Solder Joint A

A-610G 7.5.16 Components with Bottom Thermal Plane Terminations (D-Pak) says: 100% wetting to land in the end-joint contact area. Is that what you're asking about? Regards, David Fish [davef] Technical Editor & Customer Advocate

IPC calls out 100% wetting to land. I need to understand why this is needed and what functionality I will lose if I have joints at 80%

I just sold my 2 GSMs and purchase 2 new Advantis. The AC-30L is with the lightening head and a AX-72 which has a flex head and a flexjet. So I know the feeder situation very well and some of the advice you have received is not valid. Feel free to

What is your goal? To keep feeding boards regardless,or to stop feeding boards if they are not coming out?

I presume start by having it just pass into oven as soon as it is given a board from the placement machine. If I find I need to pace the boards into the oven it seems a basic PLC would be needed? Thanks for the help.

Hi Gary, Thanks for the tip, I'll give that a shot!

Tom, Mount one sensor at about 6 inch inside of the beginning of the oven conveyor and use its output as ready to accept the board signal. That 6 inch distance will give you timing and space between two boards entering in the oven. Tushar
