We always bake our loaded boards before any BGA rework is done. 12 to 16 hours at 100 c. We have had incidents in the past on loaded boards where 125 c has melted parts and the occasional low temp BGA trays. 100 c has proven safe for the past 10 y

There are pem nuts on the back side of the teddy bear face. One of them probably fell off and either shorted your main board or it is lodged in the belt and pulley that drives the advancing wheels. Take the front part of the feeder off that has the t

Thanks for the info. On the Mydata do you position the cut tape inside a feeder or place it on a tray of some sort? Here the environment is OEM R&D lab so a Mydata would be overkill in terms of size and cost. I was thinking of a smaller auto pick

There are a few questions I have before we can answer this: 1. How are the die presented to the pick and place machine? (Tape, waffle Pak, tray) 2. What are the dimensions of the die (LxWxH)? 3. Are they bumped die? 4. What is the material of the

Hi. We are having constant error messages from a Fuji QP341/MTU9 tray unit. It says there is a safety relay failed to start in prescribed time. Nothing we do seems to fix it, but rebooting enough times and eventually it goes away. We changed relay bo

Evtimov, I have yet to find any ‘good’ belt feeders. If a part is offered only in a tube we send the part out for value added tape and reel. Just make sure you specify the polarity of the part in the reel to your vendor. If that is not an option we
