for backward compatibility applications (such as this), the higher melting temperature alloy (LF alloy) gets the priority in selecting the reflow profile. you are using too low temps for reflow. your LF alloy wont reflow at these temp and you will e

Sorry theres a mistake on previous question. It should be lead free component termination but non lead free solder alloy Sn63/Pb37. The reflow profile i am using : Soaking temp. 120 to 160 deg C; time 90 to 120 sec. Peak temp. 215 to 225 deg C; time

They work well in silver conductive epoxy in hybrid applications. They are very poor in no clean applications. They don't work that well in OA solder paste either. Used them once in OA paste and in a nitrogen. They looked just fine. Solder to Pd

Hi everybody: I really need your expertise on this one. I was told that the flux 270WR from AIM is either No-clean or WS soluble depending on your needs. I read the TDS and it looks like it is....but..... Is there anybody out there using this or s

Our SMT production and storage area is air-conditioned, constant temperature is maintained but the humidity is not controlled , the raw SMT material is stored in a "Drier" cabinet, but since we assemble hybrid SMT and thru-hole PCB assemblies, the SM

Thanks for the recommendations. We have settled on the new Juki CX-1. Juki states that the machine is a hybrid between a MCM placer and an SMT placer. This machine, if it is capable to do what Juki says it can do, is exactly the machine we need. Ma

Nothing wrong with using RoHS BGAs except that the spheres won't melt/collapse at normal leaded reflow temps. Reliability will questionable. Some people use a hybrid profile with a slightly higher temp (~230C)and a slightly longer TAL (60 -90 sec).

I am thinking of having a new AOI for my SMT line. I'm considering Mirtec or Koh Young, but I have heard some issues with them. I was in SMT Hybrid Packaging in Germany and Parmi's AOI looked impressive. Does anyone know Parmi? or would you recomme
