Hi, SMTnetters, Could anyone advise where I can find information describing a method called "push-back" ( I hope this name is correct) of arranging individual PCBs into a panel? Regards, KenF

Ken, The technology you are referring to is also known as return-to-web. This panelization method involves a hard tooled perimeter die and a press equipped with an air cushion. The PCB circuit is punched out and then inserted or "pushed" back into

What is the base cost of an inline pcb etcher? Specs: fiducial alignment, smema interface, 400mm x 400mm marking area. Will be used to mark panel 2d codes, pcb array 2d codes, and human readable. Thanks Gm

You might reduce your panel size, cut it in half and rotate to better utilize your edge clamping/board supports. Tape off your current stencil and see if it improves the print. A new stencil and a little extra handling may be cheaper than tooling.

Anyone work with or have knowledge about metal core/clad boards? The board I'm working with is approximately 2" X 3/4" aluminum core pcb, in a 56 up array. There are 3 LED placements per board. I'm having trouble getting a consistent screen print.

We have a similar board and came up with a quick and dirty solution. The board locates via pins onto a manual desk press with strategically placed feet to break the mouse bite. Not really much quicker than doing it all by hand, but after a thousand p

Hi Julie, My opinion is that the top board would not pass IPC, solder mask encroachment on pads. Second board is what we call Orange peel,this can be caused two way's. 1) the solder mask was not tack dried enough prior to imaging which caused artwo

Answer on point 2 - I understand you send him gerbers of single PCB (?). In most cases you have panelized PCBs so to avoid problems with stencil first you should order PCBs and ASK your PCB supplier to send you back his gerbers of panel. There are so
