Advanced Circuits builds Single-Sided through 10 layer prototype and production printed circuit PCB boards. These printed circuit board stackups pictured are our "typical" PCB stackups for the layer count and finished thicknesses noted. However, these board stackups are not "Guaranteed" unless you so specify in your Gerber files used when placing your PCB order. Additionally, for these or any specific stackup that you require, be sure to order as "Custom" and select "Controlled Dielectric. “We process four layer boards with final thickness of 0.020", 0.031", 0.040", 0.047", 0.062", 0.093" and 0.125". You may select ½, 1 or 2 ounce inner layer copper foil for your board.

11 layer and above are limited to 20x14 and could be further reduced based on additional specifications.

We have several inner layer cores available using Isola's FR406 and 370HR materials - they include 5, 8, 9.5, 14, 18, 21, 28, 35, 39, 47, 59 and 93 mil cores.

- Six layer boards are produced in thickness of 0.031", 0.040", 0.047", 0.062", 0.093" and 0.125" with the same inner layer foil options.

- Both our eight and ten layer printed circuit boards are available in finished thickness of 0.062", 0.093" and 0.125".

Advanced Circuits can supply you with a RoHS compliant multi-layer board using laminate materials that can be matched up with the exposure to high temperatures during your assembly processes. It is important to keep in mind that some lead free assembly processes will require the laminate base material to withstand temperatures in excess of 260 degrees C or 500 degrees F for extended periods of time. To resolve this, we have high temperature laminates in our inventory so that our customers will be able to meet the higher temperature cycling requirements of some lead free assembly applications.

In high temperature materials we currently stock Isola’s 370HR in cores of 8, 10, 14, 22 and 39 mils. Advanced Circuits has UL approval for processing high thermal capacity materials manufactured by Isola and Nelco among others in producing your multi-layer board. These materials met the UL testing for 130°C maximum operating temperature, solder limits of 288°C for 20 seconds, 94-V0 flame rating and direct support of current carrying parts. Each of these laminate systems meets the minimum requirements of IPC 4101B. Individual manufacturer's material types may exhibit variations in electrical, thermal and physical properties. Normally a single manufacturer's material will be stocked for use. If you have specific questions please contact your Advanced Circuits sales representative.
