PCB edge connector

Electronics Forum | Sun Oct 19 06:42:01 EDT 2014 | timbo292832

im designing a circuit that will require the use of a edge connector so it can connect to another circuit. i need to do this so i can get both micro controllers communicating i have done a bit of research and am thinking about using a pcb manufact

Hi, To improve the Design For Manufacturing I am currently looking to write down some design rules that can (and should be) used by our engineering department. Can somebody help me get started or give some usefull tips on where

Re: Wave solder edge covers

We are wave soldering some fabs with a lot of unmasked trace area along the edges. The trace area is solid copper covered with tin / lead, no masking, no components along the edges, same on solder side and component side (goofy board design)

Min Hole/Pad distance to edge of PCB

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

First, look here [http://www.ti.com/lit/ug/snva500/snva500.pdf ] This is the actual pdf from TI, not some cheap-ass reproduction, like the link you gave us. Orange polygons [and other shapes] - copper covered with ENIG * On the edge of the board, bo

wave soldering + header connector assembling problem

Electronics Forum | Thu Nov 08 09:51:09 EST 2007 | rgduval

Where are the shorts occurring on the 96 pin connector? Are they consistently in the same areas? It looks as though there are a number of pins connected by traces on the board, and/or the ground plane. This would cause a lot of repeatable shorts i

Re: Dummy Pads for Bridging Problems

Electronics Forum | Sun Jun 07 09:58:12 EDT 1998 | Bob Willis

Dummy pads can work well on through hole parts and are often used in the Far East and on IBM products. If you take a VCR or TV board you will often see this trick being used. Alternativly you can stagger the pads at the trailing edge that works well.

Solder Bridging On SMD Pad for Nexlev Connector

Electronics Forum | Wed Oct 29 23:07:42 EDT 2014 | rajz

Help Needed. I face a solder bridging issue on solder mask define pad at edge only for nexlev connector . The pad design such as smd at four corner only. The bridging happen on signal to ground pin only. Current stencil we use 22 round with 6 mils s
