0.4mm PCB Thickness - production issues

Electronics Forum | Fri Sep 22 17:36:35 EDT 2006 | mika

A bunch of thanks guys, we will take this in consideration. BTW, we will not go for the v-grove in the panel (2x8 boards + the extra cut of areas). The board house recommended us to go for braces/hinges, since this thin pcb-panel could easily break w

A picture with 1600 x 1200 pixels nearly 900KB! Well... I think SMTnet should maximize or standardize the pixel's or image size, like many newspaper do if you want to upload a picture... I rearranged this image to a 1/4 of its original size. Compare
