Single Sided Through 10 Layer Prototype & Production

PCB Boards

Advanced Circuits, the third largest PCB manufacturing and assembly company in the U.S., 
offers the best on-time shipping record in the industry. We build Single-Sided through 10 
layer prototype and production printed circuit boards. You can use one of our "standard" 
dielectric builds or specify your own controlled stack-up. We process four layer PCB boards 
with final thickness of 0.020", 0.031 ", 0.040", 0.047", 0.062", 0.093" and 0.125". You may 
select 1/2, 1 or 2 ounce inner layer copper foil for your board. 

While our 4 and 6 layer boards are limited to 16X22 inches the 8 layer is 12x18 and 10 layer 
maximum size is 10x1 6. 

We have several inner layer cores available using Isola's FR406 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 thicknesses 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 boards are available in finished thicknesses 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, 1 4, 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 1300C maximum operating temperature, solder limits of 
2880C for 20 seconds, 94-VO flame rating and direct support of current carrying parts. Each 
of these laminate systems meets the minimum requirements of IPC 41 01 B. Individual 
manufacturers’ 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.
