Your theory is reasonable about a component issue. You need to investigate the solderability of the pads on the BGA interposer.

Actually, you will be soldering and wire bonding to the palladium layer, so we should have asked if you checked that layer, rather than the nickel. We not sure of the source of the copper that your see on EDX. It's possible copper from the pad migra

Happen to me on a conveyor after a GSM but not a PCT. Had to install small caps to kill the noise on the conveyor PLC input from the GSM. Also, might be a question of timing betweem th GSM and the conveyor.

Solder balls with wave soldering can have different causes. The two most important are the solderresist and the flux. I have similar problems, after changes the flux type 90% off all solderballs are gone. KR, Joris Groot koerkamp

We're looking for a high mix low volume paste printer. What are the Pro's and con's of the Opti Print 2020? I looked at the spec sheet and it looks like it will do what we need but usually there are issues during setup and operation. Any info would

Sorry Matt, Just hate when people use this site as their engineering bed. I believe you can weigh your board before and after reflow. It would have to be a sensitive scale though. From there you can calculate weight to volume ratios.

You can do what someone at heller mentioned to me to check if the exhaust is working properly. Take a baseball cap place it by the opening to the vent and if it wants to suck in the hat your good to go. Cost $12.00
