I looked at the tech data for the coating. It appears to need an explosion proof oven for curing (flammable vapors from solvent). I doubt the Heller reflow is explosion proof type oven.

Recently we have seen the BGA Ball collapsing issue in the field. The unit has the clean manufacturing records at factory, But in the same unit we did the cross section and found Ball explosion only in VDD and VDDQ pins. Can anyone help me to underst

Hi, Need some advice on how to eliminate or reduce the solder on finger that we are having right now. So far what we understand is that 90% of the problem is due to the reflow process where solder traps in vias causing explosion when subjecte

any advice on smt resistors and capacitor that can survive an explosive shock. the ceramic smts are not, plastic ic's and discretes do fine.

As stated above, Hydrogen is EXPLOSIVE, very bad idea. Management might have meant HELIUM, also inert.

Even if it is no where near the pumps it is probably certified explosion proof. Could they have had aluminum sheets, painted them, cured them, stenciled conductive traces, cured it, stenciled conductive adhesive, populated parts, cured it then singu

| Just curious what effect pinholes and solder voids can have on solder joints that have high current passing thru them. Also could moisture from steam sterilization (autoclaving) get inside a said solder joint and then outgas during high current, an

So, if you give your customers design guidelines and one their products causes a cataclysmic explosion, resulting in the deaths and disfigurement of many handicaped third-world children, could a lawyer consider you responsible? Spec Fir Tree General

Im not an expert at this, but im going to have to agree with blnorman. I wouldn't use Hydrogen, its very explosive. I would look into a considering a new oven to cut back on cost. Yes you will have to put out the money for a new unit, but if it reduc

We had the same trouble. We baked our boards out but the delamination continued very random. One board would be fine and the next was a nasty explosion of delam. Switched material - no problems since. I never found out the technical reason behind
