Outside the box: Can you retro your oven with a belt chain combo? I always order my ovens this way just in case. No pallet or carrier needed then. Can justify retro against the cost of the pallet or carrier. Two part epoxy instead of heat cure?

1.The bubbles appear only after the oven curing.before curing no bubbles encounterred. 2.The bubbles were very small, and can be found around the die in between the die and the epoxy. 3.Curing time is 150 degC for 4 hours.

Contact the adhesive manufacturer, or their website. Most adhesive suppliers offer two cure options - one with a belt oven profile and one with a box oven profile. The belt oven is usually a ramp and plateau of 120-150C for approx 2 minutes. The b

Some thing to watch out for is the cure spec for the adhesive. Will that match with your solder paste reflow spec? You will have two dissimiliar materials going through endothermic reactions at the same time. You could end up with under cured adhesiv

No, there's not a really great epoxy product for attaching thermocouples in reflow. Specifically, what's your problem? From Sanders Temprobe verbage ... Adhesives There are two general classes of material commonly used to adhesive bond thermoc

Roger Saunders, President Saunders Technology, Inc wrote a fairly unbiased paper that compared different thermocouple attach methods. You can probably find it on their site. In it, about gluing thermocouples, he says: There are two general classes
