Line to tie the cable system and processing

In Electronic Infomation Category: L | on February 09,2012

(1) line to the binding process of the electrical connection of electronic devices relies mainly on all kinds of wires to achieve, but the distribution of criss-cross inside the wire of different lengths, if not to organize, not only affects the appearance and SI9952 datasheet and much of the space, but also prevent electronic equipment inspection, testing and SI9952 price and maintenance. Therefore, often before the whole assembly, n...
