Hi, The solder paste is SE5-M951X-9. Comparing with the previous one we used, we are having much more tombstoning problems. The reflow profile is such as: room temp to 140C: 85~95 sec 140 to 170 C: 80 sec 170 to 200 C: 20 ~ 23 sec Above 200 C: 44 ~

We are experiencing a blistering problem during our process of lead free assembly. The customer has supplied us with the bare fab rated at 140 Tg. I am under the assumption that the Tg rating should at minimum be 170. Does anyone know if there is

Typical conveyor speeds on leaded alloys and OA flux is 2 FPM. Typical conveyor speeds on lead-free alloys and OS flux is 0.5 FPM. Temperature should be 140 F. Most polypropylene inlines cleaners should not exceed 140 F. -Mike Konrad Aqueous Technol

I am currently running at 2.12 minutes TAL using Indium 8.9HF. I am up to 68/cm min in a 8 zone oven. Indium recommends 30-100 sec or .30 to 1.40 minutes, I am think of increasing the conveyor speed until I fall with the 1.40 minutes, does anyone hav
