I am considering using high-temp ball Sn10Pb90 + eutectic solder paste for MLC reflow (no underfill). You can see that there is no Intermetallic bond for the paste and the balls. Under high stress/shock condition, the solder joints develop micro c

Hi expert, we have one lead frame product proposed to send to flux clean recently. The problem here is the frame is attached with high temp tape. After flux cleaning the frame, the tape turns out deformed in which we think it was due to chemical reac

Hello Jon (?) Sounds like it's just plain too hot. The Panasonic VA series specifies a maximum preheat temp of 160C for

I agree with Pete, I prefer to use High Temp Lubricant. Because it more clean compare to High Temp Grease. Usually i only do a few drip for 3-5 days, because purpose of lubricant is to make chain & shaft smooth.Since Biral is expensive lubricant i us

Can you use 96s solder wire on a pcb that has been plated with standard 60/40? if so what are the effects on the proerties of the 96s? If you cannot mix the two solders is there a more effective way than braid of removing the 60/40 from the plating?

Dunno about UK suppliers, how about: * Isola P97 / P27 * Polyclad GI-787 If laminates are so bloody expensive in UK, why not them have made in the States?

I should read this closer before I post it. It should read "Lead" paste not "Led" paste. This is grease for the screw shaft that brings the rails in/out on the reflow oven.
