3. Microvias. In PCB design, vias that are under 150 microns are known as microvias, which are used on many high density interconnect (HDI) boards. Designers prefer microvias because of the small size of the hole, which consumes far less space on the board than the holes that require more drilling..

General California and TSCA regulatory waste classifications based on PCB concentration are as follows: 1. Non-RCRA Hazardous: ≥5 ppm in liquids and/or ≥ 50 ppm in non-liquids. 2. TSCA-regulated PCB-Contaminated: > 50 ppm and < 500 ppm (in both liquids and non-liquids) or non-porous surface contamination with PCBs at > 10 µg/100 cm2 and < 100. Sep 01, 2021 · Level A Pad Diameter = minimum hole size + 0.1 mm + 0.50 mm (5) Level A Pad Diameter = minimum hole size + 0.1 mm + 0.40 mm (6) Minimize the number of vias required. Another good rule of thumb is to tend toward less via usage as opposed to more. Over usage may have implications for board mechanical and electrical properties..

深圳PCB设计公司-深圳宏力捷电子通过对参考设计和EVM（评估模块）中总结的一些技巧，帮助PCB设计工程师更快更容易的设计出符合规范的工程。 1. 从Type-c接口供应商处获取最新的封装并仔细检查。 在理想情况下，与PCB电路板厂一起验证接口的使用面积和平面度，为整版布局提供必要的参考。 2. 对Type-c接口进行扇孔处理。 参照之前的设计文档可以得知可以使用通孔8/16 mil过孔（没有盲孔和埋孔）。 就设计规则而言，我们将最小间距设置为3mil（最差情况）并将我们的过孔放置在（顶部/底部）。 确保通孔没有碰到Type-c连接器上的焊盘，以避免"盘中孔"的出现。 3. 在顶层和底层可以看到SSTX/RX这些差分对。. Apr 23, 2019 · Completely remove the RF box and the RF cable but keep all of the screws that held it in place. Install the mod board onto the two posts nearest to the corner of the console as shown in the picture below. Ensure that you use the nylon washers as shown (2 in the top hole and one in the bottom) before screwing the PCB into place..

A counterbored hole is easier to drill because it is simply a vertical hole. On the other hand, a countersink hole has to have a chamber angle for the flathead — usually an 82-degree, 90-degree or 100-degree angle. That said, your counterbore hole will only be suitable for socket cap screws that feature a hex hole that you would screw in with.

It is widely used and easily fabricated with no cost adders, so if you're doing a quick 2 layer board this is the via to prefer. Another type of PCB that requires this type of via is a thick PCB with a high layer count. This via can be used up to 3mm thick boards because the allowable aspect ratio of 1:10 is suitable for a 12mil (300um) hole..
