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

I don't do wave soldering but want to see if I understand the question here. Do you want previously soldered component joints melting when you wave a board? I don't think you really want that? Or is it you want to avoid it? Are you talking SMT parts?

There are a number of manufacturers of Benchtop Hot air stations. For what you are describing, look at Hakko as well as A.P.E. (if they are still around, they made a great little machine called a ?Chipmaster?, and if you added preheat, I think you

I believe you need some sort of "flat top" for this connector. I have ordered special "tops" for connectors we have placed in the past, the top is simply removed before any item is plugged into it. This also protects the connector after the board i

We place parts like this with a contact systems machine (3Z). The part comes on a reel and has a flat top on it (as mentioned above) that can be removed as soom as it comes out of the oven.

Good luck finding used. Ersa is top quality but you pay for it. The IR from Ersa is a medium wavelength thus heating is consistent across the board despite different component densities and colors. PDR does not heat the same and thus you have to be m

We place a similar square pin style of connector on one of our products. The connector is a 22mm high HW series from Samtek. We have a Yamaha YVL88 MK1 and YV88XS set up to handle them (Yes they are rebadged as Philips machines in some markets). No

Dear Sir, We are manufacturing Computer Motherboards & Networking products (which are having 2 to 3 BGA Chips onboard) in our plant. we are having 2 nos of HELLER 1800W model Reflow Ovens. this model reflow oven is having 9 heating zones at both top

I have been looking into buying a rework station like ERSA or PDR. What I am questioning is how well will these systems reflow BGA's with metal top/cover that are reflective. In addition, when preheating the board would dark body packages absorb te
