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 ~

Also, I was beginning to think that the humidity level in the facility was a factor.. but I don't believe that's the case.. as this condition seems to occur regardless of the humidity level.. Equipment being used is as follows.. Metcal BGA 3500

Michael: "C1005" stands for Capacitor 0402. For the package 0603 you need to choose "C1608". This is out of IPC-SM-782. I don�t know where it�s coming from we also deal with 0603 or 0805. IPC uses RLP-numbers (Registered Land Pattern Number) to ident

Micheal: Correct me if I am mistaken, but I think you have stumbled onto the age old battle between metric and imperial representations of component packaging. I have to deal with this every day as my machines are metric and the designers use imperia

I am looking at two different type fluxes, Kester 951nc and AIM 264-5nc. The two seem to be comparable, but the Kester is listed as an ORL0 and the AIM as a ROL0. My product builds are all military and I have been dictated to use only ROl0 flux. I kn

We are a small CM doing mostly prototype and small production runs SMT and PTH. We have an old Hollis machine works well when we need it. The foam level does not come up to the board level, even with the air cranked up full. We are using a synthetic

Thank you guys for your help, I do not clean any on my assemblies who are build by the SMT an wave soldering department, we do used liquid fluxes Kester 951 and cored wire keester 245, usually it�s for batteries connector, led, terminal and wire rap

Hello I am having a problem with the flux in the wave solder, I am using a sonoflux 9000 this machine uses a air knife to spray the flux, it creates a mist that when hits the air knife pulls the mist up to the pallet where the board is, but for som

Hello, We are buying a Vitronics-Soltec wave solder machine with a spray fluxer to replace our old Econopak that has a foam fluxer. Currently we thin our flux (Kester 951) in the foam fluxer per Kester PS-20 and PS-22 test kits with kester 110 thinn

Jake, The No-cleans on the market, to me, still aren't as good as OA and water wash. But they have gotten better. The type of No-Clean flux and paste to use really depends on each individual assembly, the machines used, settings, and the environme
