In 1903, a German inventor, Albert Hanson, described flat foil conductors laminated to an insulating board, in multiple layers. Thomas Edison experimented with chemical methods of plating conductors onto linen paper in 1904. Arthur Berry in 1913 patented a print-and-etch method in Britain, and in the United States Max Schoop obtained a patent[40] to flame-spray metal onto a board through a patterned mask. Charles Durcase in 1927 patented a method of electroplating circuit patterns.The Austrian engineer Paul Eisler invented the printed circuit as part of a radio set while working in England around 1936. Around 1943 the USA began to use the technology on a large scale to make proximity fuses for use in World War II. After the war, in 1948, the USA released the invention for commercial use. Printed circuits did not become commonplace in consumer electronics until the mid-1950s, after the Auto-Sembly process was developed by the United States Army. At around the same time in Britain work along similar lines was carried out by Geoffrey Dummer, then at the RRDE. 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
