I assume you using a fixed mass vapour phase system? Yes rates of rise are impacted by the mass of the PCB, larger the mass to mass of vapour phase the lower the rise generally. So if you load the machine with very little mass PCB rise times can be

We used to use an APS Gold GF-120 before we went lead-free and the HT version came out. It worked fine for low volume and proto runs though not as much control over the profile as an oven with more zones. We actually had a batch oven from Bomir befor

As with so many things, some brands work very well on high density, low profile assemblies and some do not. Because my company manufactures these machines, I don't want to use this forum as an advertisement so I will recommend the following: 1. Sen

Is the stiffener a piece of FR4, or a component that needs to be installed? We've done a number of flex assemblies taht have a rigid stiffener, generally a piece of rigid flex, or FR4 that has the components mounted on it. This type of stiffener

I just swapped from the HASL to Immersion Silver mainly because the board house we use could not maintain consistency in keeping the pads level. I was constantly battling bumps and bad finishes on the pads. They are able to give me a consistent board

Hello All, looking for some help from you guru's. I have several Enig boards with solderability problems. Components ranging from 0402's to ssop's. Using AIM W/S leaded solder paste, profile is beautiful and has been for years running the same produc

We are having a little trouble with what appears to be a crystalization between our fine pitch parts. The problem appears after a a thourough wash of the pcb when dry. It looks like lead wiskers/haze between the joints.We are using water soluable lea

It is pretty hard to wave solder fine pitch parts bad enought with 0.5mm let alone 0.4mm It can be done but need N2 inert wave soldering & need layout design to accommodate this... Iy it is a QFP need to run part 45 deg into wave and if possible in

TK, Hope you got it right only for this round of assemblies. Well, passing through a Reflow belt is not an ultimate process to dry circuit cards & take out moisture from Solder finished layers. First of all, if the packs were not unsealed (even s
