IOW, profiling good, here's some stuff for sale.

starting point with zone settings would be, 100 / 160 / 200 / 225 / 260 deg C...but you'll have to check the exact profile on the pcb with a reflow profiler....making sure you meet the paste spec and making sure you don't heat any devices up to quic

183C, 60 +- 15 seconds). The quesiton to use a straight ramp or soak profile comes down to the product your are soldering. The key is to get the whole assembly at the same peak temp (minimized delta) and same TAL for effective formation of the so

First and fore most is to find your paste manufacturer spec sheets. Read it over several times and let it all sink in. Then call them with questions as they want to keep your business so their engineers want to help you use their product. I assume y

We do both our ovens once a week. If something looks out of tolerance (we've developed acceptable tolderances based on many recorded profiles over time and oven mfg. specs.) we wait a couple hours and try again. The recorded data over time is very

We've got an auto fuse clip (a pair of tin/nickle spade type receptacles joined with a nylon bridge piece) giving us fits. The pins on this thing have a right angle profile (symmetrical "L" shape) and make great flux traps. No amount of tweaking pre

Dave, I sand corrected since I know you wouldn't steer me wrong...although the lst time I looked at the IPC spec for a solder profiel it was still designed for older generations of paste and were specifically water wash biased although that doesn't c

Snehal, Look at the spec sheet for the paper phenoline PCB. Look at the max temp. If it is at or lower than 183 degrees C, here lies the problem. If it will withstand higher temps at a shorter durration, you can possibly speed up the belt but like D

First things first. Check the manufactures specs on the electrolytic caps as they may not be able to handle the lead free temps.

we are using a "recommend supplier profile", and we have gotten back to the talking table with them over this profile specs. Thanks for the pointer, have ask them on this issue. Have also asked for their phase-transistion diagram to understand their
