| A user of one of our components exceeded the floor life of some plastic BGA components. They did do a pre-bake prior to SMT reflow but only 72 hrs at 40C and not the recommended 12 hours at 125C. I've recommended accoustic microscopy to look for po

While trying to sell me a low temperature baking system for SMDs the salesman mentioned that the 125C for 24hr bake had been known to cause co-planarity defects. I thought I'd ask some experts. Any help guys?

Looking for a company that makes a small batch reflow oven. Not a belt-style convection oven, but a cabinet style that can 125 c to 150 c. Thank you

Paul, You might check out the "McDry" line of humidity control devices. They are marketed through SEIKA Machinery, Inc. Give Hiro a call @ (310) 540-7310 Ext. 125 He has been a real good resorce for SMT solutions. Jonathan

I think there are guidelines for baking in J-STD-033. Contact Francois Monette, Cogiscan Inc., 450-534-2644, fmonette@cogiscan.com With the 125�C for 12 hours, er whatever, bake you are trying to strike a balance between: * Removing the moisture f

from my humble experience : 1) check if there is nickle contaminate in the gold bath? shd have report data from the PCB fab house. 2) check if your production did 48hr bake at 125degC, IF the BGA did not come in its "original" MSD cozy packaging.

Hi, I have taken the profile.The peak temp. at the lead terminal is 219 degc, duration above MP 54 sec and duration 125 deg C-160 deg C is 60 sec.

Tony First, drying at 125*C for an hour is not going to do much drying. Heck, those boards are barely warm to the touch. Second, tell us about: * Pitch of your uBGA * Solder paste flux * Cleaning process and agents
