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

We used to do this kind of stuff in vapor, but do none now [although the imagination doesn�t have to turn too much to envision doing it again]. Start here: * http://www.bergquistcompany.com * http://www.gouldelectronics.com

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.

I wouldn't raise the temps just slow the conveyor, You need to get the PCB "soaked in". It seems as if you are applying more thermal energy than the PCB can accept in all areas. Does this oven have convection heating? Hopefully so. I have found t

Thanks Mr.Dave. Sorry for the delay. One of our major prolems in ENIG plated surface is that wire does not stick. For many years we were getting a bond strength of 14 grams in both ENIG and electroplated surfaces. Now one vendor supplies ENIG boards

Try using Chip Quik to reduce the heat required for component removal. Along with your bottom pre-heater, use a temperature controlled hot air system to help heat up top side for component installation. http://www.pcb-repair.com/products.htm

We are working with .065" thick metal core PCB's. I have a couple boards that are in need of rework. The components we are placing are similar to a SOJ package with a solder pad underneath the component. We are also using a lead free process. I have

The high thermal mass of metal core boards makes them difficult to heat with hot air convection heating or IR. So, edge heaters are used for effective heating of heavy core circuit boards. Hakko and VJ Electronix offer edge heaters. We imagine othe

You cannot use diamond cut routers on aluminium. They will clog up in seconds.. You have to use "endmill" type. These are available from all PCB drill/mill supplier, nothing fancy. Depaneling - you mean cutting only tabs, not full perimeter ?

Page 18 http://www.mpk-pcb.de/en/download/mpk-kemmer-pcb-tools-catalogue-2019/ And maybe try "downforce" EA30-L type, as the cutting path is very short. Short lengths you can cut dry. Just use manufacturers recommended feed/speed and DO NOT reduce
