The hole is made conductive by electroplating, or is lined with a tube or a rivet. High-density multi-layer PCBs may have microvias: blind vias are exposed only on one side of the board, while buried vias connect internal layers without being exposed on either surface. Thermal vias carry heat away from power devices and are typically used in arrays of about a dozen.A via consists of:Barrel — conductive tube filling the drilled holePad — connects each end of the barrel to the component, plane or traceAntipad — clearance hole between barrel and metal layer to which it is not connectedA via may be at the edge of the board so that it is cut in half when the board is separated; this is known as a castellated hole and is used for a variety of reasons, including allowing one PCB to be soldered to another in a stack. Company ProfileWe know almost all electronic engineers got a problem to found a right manufacturer to make  PCB prototypes & small batch order because big factories don't want to make small orders, they always gave high price and very long delivery time, they can't provide fast delivery service. The small factories gave low price, but their quality control and service/English communication are not good, they can't meet customer’s request also. This is why we made JETEK and we are committed to make JETEK become a professional PCB supplier with rapid response、sincere service、excellent quality and reasonable price. Of course we also accept high volume PCB order.JETEK’s engineers and workers are most have many years working experience, we supply our products all around the world. We have perfect processes to allow you to get the high quality PCB with door to door service with fastest turnaround, all of our PCBs approved by ISO9001/TS16949 and UL certificate.Our Vision is to help people around the world to get high quality PCBs on an Easy & safely way.Our advantage is Fast delivery time & Reasonable price & excellent quality & Professional service.For the convenience of customers, we have the value-added services on Laser SMT stencil & PCB assembly.Contact us now to get the best quality PCBs at cheap price & easy way!  Contact informationsales@jetek-pcb.com
