Sorry looking at your profile again and considering its Aluminium substrate I would opt for an increase to the preheat or introduce a soak to the profile to get the PCB up to reflow. Try soaking between 175 - 200C sufficient enough to heat the whole

yes something like this, but Bliss is located in the US and we do not Need the big mounting plate. only the steel or aluminium runners Kind regards

You cannot use diamond cut routers on aluminium. They will clog up in seconds.. You have to use "endmill" type. These are available from all PCB drill/mill supplier, nothing fancy. Depaneling - you mean cutting only tabs, not full perimeter ?

We buy PCBs for aluminium wire bonding. Our PCBs have 0.25 mm square pads for bonding and 0.10 or 0.15 mm gap between circuit traces/tracks. We do not have any problem. Our vendor gives 9 microns of Nickel and 0.03 microns of gold.

ENIG is a common solderability protection on BGA packages. Pd/Ni/Au while more expensive could have advantages over ENIG in the following area: * Allow both gold and aluminium wire bonding * Better solder resist compatibility (63�C max) * Might take

I would like to know if ENIG is widely used for the thermosonic gold wire bonding or this application is an exotic one. And I also wold like to talk to someone who uses printed circuits with ENIG finish for such an application. I do not quite underst

Any materials that come in contact with the flux should be made from stainless steel, titanium, or plastics. These materials will not corrode from OA fluxes. Overspray is an issue. I think Pillerhouse has that jet fluxer, so I don�t think there is mu

HI, thanx for opinion ;) tried Searching but obviously did some mistake in 'words' and got 0 results ;p I've already tried high temp solder - but it's damn difficult to solder TC to the component... I'll try aluminium then...but from what I rememb

IF and only IF you are on a solid flooring. We have ESD carpet. If you were to apply RTV to the carpet, you'd be walked out and thrown on your skinny a$$. Also, extruded aluminium conveyors will bow before skidding, thus causing alignment problems
