I forgot to update this. Customer insisted on reflowing SIM card directly to PCB, as per their previous CEM. It worked. No deformation of the SIM card - assembly works - records data to SIM card. Note that using hot air reflow type (rework station)d

Hi! I have been studying the reflow process. And now, I am researching for a recommended reflow oven that can process a small to low-medium production SMT soldering. For the experts in the reflow field, please recommend a reliable reflow oven. Here

Hi Everyone What lubricants do your maintenance people use for the chains in your Reflow ovens? The manuals for our ovens have one recommendation - but I am always open to other people�s experiences and recommendations. Another option may be easie

Grant, The best rule is- "If it works don't touch it". What I mean is check your component datasheet. Max allowed temperature should be there. You know the profile of your reflow oven and the temperature reached during reflow. So if there is no conf

Hi! I'm a process engineer attempting to do a capability study on our existing convection reflow oven - Heller 1500. It was recommended by an independent consultant to do at the very least, load testing, process ready testing, and board uniformity h

Thank you very much, Dave and Steve. I got paste and wire from Indium and Qualitek. Are there anybody with high-temperature reflow experience (330 degree C)? Is it OK to use Regular Convection Reflow Oven (We have a Conceptronic HVC 70, 5 zones) ?

I have encountered poorly designed BGA packages that cannot be removed or replaced with BGA rework tools. I discussed this with the package designer. He recommended reflowing the entire board. I was finally able to remove the part by preheating the

Have you tried to run the same process but with diffrent solder paste manufacturer.? This give you information whether paste is ok. Try also print paste on the bare board and run through reflow oven. Check 2-3 boards. Is it the same places where i

Absolutely ok!! We already co-use the same profile setting for top and bottom side to avoid line efficiency loss for more than 10 years. But only one thing you should careful is the heavy mechanical parts on bottom side may drop during reflow proces

Perform profiling with a product where the LED is placed more than on another products. You get a valuable case with a higher delta T and possible maximum reflow temperature must use, etc. This profile will be used for similar products. You need to o
