One of the most important factors for being able to make a circuit Underwriters Laboratories: board with very fine traces is knowing before you start, how much All materials meet UL-94VO copper is onmy boar d General Information: Undercutting of your traces during long etch times is what destroys fine traces. The longer the etch, the more the undercutting - its MIL-P-13949G Type Designation GF a straight line proportional problem. So, the lower the amount of U.L. Designation ANSI Grade FR-4 copper, the finer your traces can be. As an example, all commer- U.L. File Number E38534 cially produced boards that have incredibly fine traces (on the order Flammability Rating 94V-0 of .002 to .004 widths) actually start off using copper laminate 0 Maximum Operating Temperature 130 C with 1/8oz copper. The etch time is very fast which doesnt give Copper Weight 1/2 oz. the etchant enough time to work sideways under the etch resist (ie undercutting). The board is then plated-up to 1oz (or 2oz for MilSpec)befor e being sent back tothe customer . Peel Strength: As received 10 lbs/in, min For our purposes here, plating up is totally impractical due 0 After Thermal Stress (550 F, 20 sec) 10 lbs/in, min to the complexity of additive plating, so the next best thing is to After Processing Solutions 9 lbs/in, min have the copper reduced to a reasonable level which in our case At Elevated Temperature 8 lbs/in, min is 1/2oz copper. You still have plenty of resolderability without traces being damaged and decent current carrying capability with the big advantages being that you can image down to .008 (and Difunctional FR-4/G-10 Properties: even.006 if you are very clean in the boards preparation) and Flexural Strength Lengthwise90 KSI, min the board is very easy to cut using a paper cutter since its .032 Permittivity, 1MHZ 4.7 max thick vs064 thick. The trade-off from using a lesser amount of Loss Tangent, 1MHZ .015, max copper is reduced current carrying capability. Most users are low Water Absorption .15, max voltage, low current so this isnt a problem, however, if you require high current traces, all you need to do is slightly widen your traces.
