Thickest internal copper layer?

Electronics Forum | Tue Jan 15 10:19:39 EST 2013 | boriskilk

For a multilayer board the thickest internal copper layer we will do is 0.062".

Matt, have you run a profile on this board? Just because it's .062" doesn't mean that any old .062" profile will work. We have .062" thick boards that almost nil for copper and other are utilizing 2 oz. layers internally. They require quite diffe

Chrys you're fine. On scoring: * Be sure spec material remaining, not what is removed. * Be sure that the v-grooves are perpendicular to each other, not off set. * Typ spec for for .062 thick boards FR-4 0.018-0.024 MC-3 0.030-0.040 * HADCO recomm

I saw a post from last year that quoted Hadco. For a .062" thick PWB, the remaining material was .012" +/- .002". This is close to what we have been using, but some PwB vendors are now asking for .020" +/-.005". This seems too thick for smooth bre

This flex is .001" Kapton polyimide. The flex portion of this rigid flex consists of 3 layers of 1 oz copper with 5 layers of Kapton. Part of the flex is sandwiched in standard FR4 with two layer of copper on each side for a finished thickness of .

Russ, I feel a little better now.... Baking specs...... Can you give me a tip on where to look? It's a 4 layer, .062 and roughly 5 inches square. Thanks.

Is anyone using .062 aluminum circuit boards with copper conductors in your production lines? What kind of reflow profile is required? What special considerations are there to be looking for? I am asking for any information you can give me. Thanks

Cracked Capacitors

We are experiencing cracking of 1206 .1uf/50V capacitors on our boards. Design is keeping the caps away from the board edge 0.200 and perpendicular to the longest edge but still they crack even in the interior of the board. Recommendations? bds are

Copper thickness measurement

Electronics Forum | Sat Dec 10 07:03:59 EST 2005 | mdemos1

Hi. I am trying to find out the minimum copper thickness I should see on a through hole barrel. The board has 1 ounce copper and the board thickness is 0.062". I am finding thicknesses of 0.6 to 1.2 mils. Thanks, Mike.
