PCB History 2
Before printed circuits (and for a while after their invention), point-to-point construction was used. For prototypes, or small production runs, wire wrap or turret board can be more efficient. Predating the printed circuit invention, and similar in spirit, was John Sargrove's 1936–1947 Electronic Circuit Making Equipment (ECME) which sprayed metal onto a Bakelite plastic board. The ECME could produce 3 radios per minute.
During World War II, the development of the anti-aircraft proximity fuse required an electronic circuit that could withstand being fired from a gun, and could be produced in quantity. The Centralab Division of Globe Union submitted a proposal which met the requirements: a ceramic plate would be screenprinted with metallic paint for conductors and carbon material for resistors, with ceramic disc capacitors and subminiature vacuum tubes soldered in place. The technique proved viable, and the resulting patent on the process, which was classified by the U.S. Army, was assigned to Globe Union. It was not until 1984 that the Institute of Electrical and Electronics Engineers (IEEE) awarded Mr. Harry W. Rubinstein, the former head of Globe Union's Centralab Division, its coveted Cledo Brunetti Award for early key contributions to the development of printed components and conductors on a common insulating substrate. As well, Mr. Rubinstein was honored in 1984 by his alma mater, the University of Wisconsin-Madison, for his innovations in the technology of printed electronic circuits and the fabrication of capacitors.
We 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.
