We are reflowing boards that have glop top components mounted on them. Do glop tops have the same moisture sensitivity as fine pitch? Should we be baking the boards prior to reflow?

Anyone knows about the top side remelting requirement for wave soldering process? Is there any standard & procedure to follow? What temp can cause the solder for top side to re-melt?

I also operate a 3/45. In order to flux from the top, you would need to have another system on top similar to what you already have on the bottom. There just isn't room for all of the required equipment. Who did you contact at ERSA? I have always had

The temperature that will melt solder holding top side SMT components during wave soldering depends on the alloy of that solder. So, for example, you'd expect: * Near eutectic SnPb solder to melt around 215*C. * LF to melt around 240*C. It's common

Does anyone know if the ERSA 3/45 can be supplied with top side fluxers? I haven't heard back from the co after my inquiry.

Yes, I have tested some boards, and found that most QFPs which near the via will have the higher temperature. One of my customer requirement is to have the temp less than 200 deg C for top side. We were using the hi temp wire to solder the QFP's for

Unless those vias are used for ICT or test.
