Is more a guess but, your drawing is missing things, more precise the legends on the edge of the drawing, but for what I can see the diameter of the ball is 0.30 +- 0.05 hope it helps!

Three main groups of depaneling equipment are: 1 Scoring: Limited to straight edges and mainly 90� angles 2 Routing: And a cloud of dust 3 Singulating: Hard tooled by board To get started understanding the suppliers look here: http://www.cassembly.c

Assuming you are talking about solderable surfaces: People specify various materials to protect the solderability of the pads on the board. Gold, actually, Electroless Nickel - Immersion Gold [ENIG], is popular. * Board fabricators like it because

We have a PCB with the dual sided connector that slides on from the edge and has leads on the top and bottom sides of the PCB. It has 20 leads on each side of the PCB with with about .8mm pitch. The PCB also has a gold grounding strip on the edge fo

Assuming agressive design rules what is the minimum distance I can get away with between the board edge and a SMT pad and between the board edge and a plated mounting hole ??? (The board is only 1"x2" and the mounting holes are 80 mil dia, 125 mil

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.

Our preference has been ENIG. We find that we achieve higher quality (visually) soldering for through hole and surface mount parts, with less handling issues than when we use white-tin, or immersion tin. We are about to do a test on some boards tha

Hello mickd, For Fuji practice, the primary tooling hole preferably be 5mm from the edge of the PCB (lower right hand corner). This is the reference X0, Y0 co-ordinates in the Fuji program where placing co-ordinates going LEFT will be -ve value & go

Hi! Can anyone tell me what is the min spacing between PCB edge & land pattern to avoid cracking of components due to mechanical stresses caused while depaneling with cookie/pizza cutter. Thnx!
