It needs to be in Excellon CNC Drill File format. The file that is used to program the CNC drilling equipment is not a Gerber file. (We can also accept 274D Gerber or ODB++ formats). The copper patterns, solder mask reliefs, silkscreen, board outline and even fabrication notes should all be in 274X Gerber format. Your Gerber files are used to print the images needed on your PCB. What file format should I send for my drill file? If your design has more than 10 drill hits per square inch, please check with us before placing your order since this may require additional cost. Since more than 95% of designs have less than 10 holes per square inch, we opted to streamline the quote process and not ask for the total number of drills. Where do I enter the number of holes on my quote? Unlike some PCB shops, we don't restrict you to a few 'standard' hole sizes. 250" (6.35mm) and larger will actually be routed with the CNC router. We have a wide range of drill bits so we can drill any size hole from 4mil (0.1mm) and up. Does it cost more for smaller holes?ġ2mil (0.3mm) and larger holes have no extra cost.ġ1mil-7mil (0.28mm-0.18mm) holes will carry a small premium.Ħmil-4mil (0.15mm-0.10mm) holes are considered microvias and will typically need to be laser drilled and would need to be custom quoted. Contact your sales rep if you have concerns about min hole sizes. If you require a thicker board, then the minimum hole sizes will change depending on the thickness required. Mechanical bits simply aren't strong enough to drill through the laminate without breaking or deflecting (bending) when the bit has a very small diameter.īe aware that these minimum hole sizes are assuming standard. Min finished size for a laser drill is currently 4mils (.1mm). Anything smaller will likely require the use of a laser drill. Any finished hole that is 7 mils (.178mm) or larger will be drilled with a standard mechanical drill bit. There are 2 types of drilling equipment, mechanical and laser. NPTH (non-plated thru holes) will be +/- 2mil (+/- 0.0508 mm) What is the smallest hole you can drill? PTH (plated thru holes) will be +/- 3mil (+/- 0.0762 mm) ![]() What is the tolerance on finished hole sizes?Īt PCB Universe, we follow IPC Class 2 standards. For instance, if you have a 6 layer design with a blind and buried construction per the picture, we would need 4 separate drill files. Microvia – This is a very small hole that is laser drilled, is between 4-6mils (0.10mm – 0.15mm) in diameter and is usually either blind or buried.Ī separate drill file needs to be supplied for each set of drills that needs to be blind or buried. In a 4 Layer board, it would connect L2-元. ![]() On a 4 layer board, a blind via might be drilled only from L1-L2.īuried Via - A via that is invisible from the surface of the board. See below a selection of x-ray vision gadgets.Thru-hole Via – This is a standard hole that is drilled all the way through your PCB.īlind Via – A via that is visible on an outer layer but does not pass all the way through the board to the other side. These xray vision glasses look like a normal pair of glasses. The images are shown and recorded in real time and as you can imagine, gives you great flexibility to move around. ![]() Works on the same principle as the camera described above, with the exception that these glasses can be worn and also records images if you have a portable recorder. These are transparent glasses that can see through clothes. ✅Buy now / Learn more ✅Xray Vision Glasses (Goggles) They should not be used for indecent actions. They are great for law enforcement operations, banks and jewelry stores as well as detecting forged documents. An xray vision camera can even see through the makeup of a woman. Xray cameras work on the principle that visible light is filtered out and only the infrared and other parts of light are captured, making it possible to see through clothes and certain objects. The ability to see through clothes and objects like dark sun glasses or dark windows makes this infrared device ideal for identifying persons and objects. They are very small and have the ability to see through clothing and objects. ![]() If you don’t have a Sony Nightshot camcorder, it is also available. No extra modifications needed, except for the filter. Transform your Sony night shot or Panasonic night view camcorder into an xray vision device by using special filters that are easily screwed on.
