45 seconds from 230-245C. Check your paste material of choice for recomended profile peak temp and TAL. If you have not selected a lead free material check out the major paste suppliers on their lead free material offering and review the specs.

It's possible your supplier has not thought through the results of their conversion to lead-free throughly. We'd expect something like: Reflow Parameters||Pb Assy||Pb Free Peak Temp.||235�C �5�C||255�C �5�C Time Within 5�C Peak Temp.||20 to 40 sec.|

My company now sells the EVS solder recovery system. Yes, there are companies reclaiming lead-free. Hopefully an actual user will respond to your post but you can feel free to email me if you want me to put you in touch with an end-user. cycorda

If there has general standard to guide which type of component can not be cleaned ? No-clean flux be used in solder process ,and the PCBA we build be subject to the filed of high frequence (13.56MHz). Is it very critical if the coating that adhered

Hello, I am looking for industry time standards for assembly tasks, from SMT to product packing. I was told a few years ago that IEEE had these standards. When I finally looked, they did not exist that I could find. Does anyone know if / where such

Steve, I have also requirements for this machine. I was able to evaluate some of these machines but the result was not ok. It burn the PCB especially if you have 5mm thick PCB. If you can find one that doesn�t burn PCB please let me know as I am als

I think you would be better off designing routing slots into your panel and then use a high speed router to cut out the PCBs. PMJ Automec/Cencorp make such equipment (I used to work for them) but have no affiliation to them anymore. Alot of peopl

Does anyone know of any resources I could investigate to make a small circuit that would consist of a transmitter, receiver, and a motor. I want to be able to press a button on a remote control and that would make the motor turn on, then I want to b

Is there anyone who knows the yield rate difference for SMT on multi-flex boards and rig-flex boards ? Basically, I think the yield rate should be higher for rig-flex than multi-flex due to the poor dimensional stability of polyimide, since multi-fle
