Drilled Holes in the PCB – all you need to know to avoid surprises. 1.Tool lists for drill files are ALWAYS read ( and interpreted) by our CAM systems as finished hole sizes ( so final diameter of the whole after plating and surface finish )
A Drill Chart of hole locations, sizes, and access hole diameters with tolerances. A material cross section (circuit stackup) specifying thickness of each layer. A photocopy of artwork or CAD data (if available) showing conductor layout and widths, with all applicable tolerances. All testing, inspection, and packaging requirements. ;
When using a drill bit for a feeler gauge, please remember that many drill bits are actually undersize at the shank end of the drill bit so please use the above bit sizes with a grain of salt! Also note that to correct for a broad feeler gauge or a loose-fitting drill bit: ROC = (D 2-W 2) / 8T Where:
PVC Pipe sizes are different than the size the pipe is called. For example, a 1 inch PVC Pipe is actually 1.315 inches in outside diameter, and 1.029 inches in inside diameter. Fittings follow this same pattern, a 1" fitting has a 1.315 inch opening to accept a 1 inch pipe, which actually measures 1.315 inches in diameter.

Polyimide Cover ... Now look thru your list of hole sizes and compare the minimum guaranteed size for each of them to the maximum diameter of the lead. Specify the smallest drill size where the minimum diameter hole is larger than the maximum diamter lead. If both come out to the same value, use the next higher drill size. For other size or type vias, the current capacity can be estimated by equivalent trace capacity, where the trace width can be calculated by: diameter*3.14*0.6. For example, a

Sep 17, 2013 · If possible, always use at least 4 layer PCB. There is not much difference in cost between 2 and 4 layer PCBs, but 4 layer PCB is much better. Recommended for breakouts, small and simple boards. Don’t use for CPU boards with memory interface, but it’s fine for Base boards or some microcontroller boards. 6 Layer PCB – Cheap and large boards Using an extra piece of PCB, and using those eight larger sizes, I drilled three holes for each size. A picture of the PCB is attached. Then, using my "pile of parts", I put each wire through the hole that it fit "best" in, then on the same spreadsheet put an "x" in the sizes that worked for that part. Motherboard Size Variations. Picking the right motherboard can be a confusing task. There are many different sizes of motherboard available in the market, and the size of a motherboard has a direct relation to what type of build a motherboard will be best suited for. Here is a detailed Motherboard Size Chart that explains all of your questions.

How to Use this chart: The table of Wood Screw Specifications simplifies the selection of the bit or drill size best suited to your requirements. The fractional equivalents and undersize/oversize decimals indicate how close a bit of given fractional size will bore to the actual screw dimension, and whether the fit will be snug or loose. This chart lists the recommended hole sizes to use with your printed circuit boards. ... Use chart to determine PCB hole sizes for common Samtec lead sizes. Jun 17, 2011 · It's no good to make a wide trace and large pin hole and then have it end in a ground plane with thermo-traps enabled - just 4 very thin traces of copper instead of a full ring. Otherwise - if the trace can take the current the via can too (general rule of thumb of course). PVC Pipe sizes are different than the size the pipe is called. For example, a 1 inch PVC Pipe is actually 1.315 inches in outside diameter, and 1.029 inches in inside diameter.

Jan 08, 2013 · SolidWorks Hole Wizard is pretty complete when it comes to industry standards for hole sizes, but what happens when you want a hole size that isn’t in the list? Not a lot of people are familiar with SolidWorks ability to add custom hole sizes to the Hole Wizard database. So let’s see how that is done…. In PCB fabrication the aspect ratio is the thickness of a PCB divided by the diameter size of a drilled hole — see Figure 1 below. It’s importance relates to the plating process — plating solutions must flow through the hole efficiently in order to achieve acceptable copper plating . Using an extra piece of PCB, and using those eight larger sizes, I drilled three holes for each size. A picture of the PCB is attached. Then, using my "pile of parts", I put each wire through the hole that it fit "best" in, then on the same spreadsheet put an "x" in the sizes that worked for that part.

• Place a minimum of two holes in opposite corners of the board. • Tooling holes should be non-plated. • Tooling hole size tolerance of +0.002" / -0.001". • Tooling holes should be placed asymmetrically to prevent the test operator from placing the PCB on the fixture backwards and damaging the test equipment. 10.1 Manufactured PCB Dimensions [90] The range of dimensions allowed for each type of PCB construction is shown in table 11.

With larger via sizes (0.016" and up) in a 0.062" typical thickness PCB, achieving a Type V or VI via plug is not too difficult--though still time consuming. However, trying to screen a low shrinkage ink into a 0.012" via (and often down to 0.008") and fill it entirely is a much more difficult target to hit.

Holes with a copper pad on one outer layer but not on the other are not accepted. Hole Sizes & Quantity: All hole sizes between and including 0.010” and 0.247” are available, up to tolerance. Limit number of holes to less than 50 per square inch. Hole Tolerance: These sizes are the finished hole diameters after plating. PCB Capacitor (as defined in §761.3): any capacitor that contains >500 ppm PCB. Concentration assumptions applicable to capacitors appear under §761.2. PCB Container (as defined in §761.3): any package, can, bottle, bag, barrel, drum, tank, or other device that contains PCBs or PCB Articles and whose surface(s) has been in direct contact with PCBs.

Surface-mount technology (SMT) is a method in which the components are mounted or placed directly onto the surface of a printed circuit board (PCB). An electronic device so made is called a surface-mount device ( SMD ). Hole sizes and count of holes: Aggressive hole size and drill size, along with non standard trace width and air gap can increase price of standard thru hole technology compared to the cost of more simple HDI Technologies. Small hole size and thick PCB (high Aspect Ratio) increases drilling time and the drill erosion which results in higher cost.

Printable map of asia pdfThe min hole size in Fusion is from 0.2mm to 0.3mm. Normally, the average requirement for drill hole is 0.3mm. Strict equipment is needed for the factory if smaller hole size required. 3. Electroless plating copper After the second step of drilling hole, there is no cooper inside the hole, which means the holes are not contacted. I'd size the holes about .005 over the wire diameter. If that doesn't land you on a fractional or numbered drill size, just round up to the next highest bit. if the holes are plated through, you will need to take the plating thickness into account when specifying the size.
