Dear SMTnetters, I've been told to have a look at finding a machine that could mill the leads of all PTH components to a certain height on an assembeled and soldered PCB. PCBs should be inserted in one side of the machine and come out milled on the

A few years back when I was working in a Hybrid company we used carriers machined from aircraft grade aluminum. Its easy to machine on a Mill doesn't bend so easy when mishandled.The thing to know is do your flex circuits sit flat when placed on the

To prevent cracking SMD components near the edge of PCB you should use guillotine for V-cut groove. Other solution is redesign panel of PCBs and in critical areas you should mill along the outline instead of V-cut, but if you choose this way probabl

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 ?

I've never lost memory in a BGA from heat removal. However we can create a profile on our BGA rework stations to remove using bottom heat only. This exposes the BGA body to temperatures of around 190 to 200C. I have a colleague that has a machine

Thanks Davef, we are using a mill max pogo pin on a small pcb that is panelised into a panel of 50, we have had a jig designed to get them straight instead of hand placing, there are 4 per pcb. We have followed the manufacturers guidance for stencil

You'll find a lot of guides for cutting aluminium on the internet but basically, try and use a bigger end mill if you can, keep it at the right speed (not slower). We cut 1.6mm aluminium with a 3mm end mill. Smaller end mills didn't evacuate the chip

Hello, Is anyone using an SMT pick&place machine to insert single contacts into PC boards? I have some boards that have 32 female contacts for 1mm pins, and 16 contacts for 0.5mm pins. I have been using Mill-Max for these contacts, getting the sma

We used durastone pallets, where you mill out the profile of the panel or board and it sits flat for printing. We secured them using 3M spray mount (for singled sided) and Kapton tape. Obviously helps to have bottom side heating in the oven as you

d0mino, Given the fact that the SLIMKic has built in wave detection, you can just make a pallet out of 10mm delmat material, and drill a couple of holes on the pallet for the wave detect T/C's (ports 2 & 3 for left and right). All the wavesurfer is
