1. Flexstrip Cable RFC(Round Flat Cable） JUMPERS
“ Round flat cable/Jumpers”, the brief name is RFC. It is a kind of new data cable that it is to be make with Nomex paper, PET insulate material and plate round-flat copper wire of tin thinly. It can communicate in two PCB with
welding and not need connector. it has many advantage, such as temperaturer-resistant, a flexible, curve to fold , the thickness is thin, link in brief and solve electromagnetism to shield (EMI) easily etc.
It is the most suitable for move the parts to main board 、board to board ,make a data to deliver through a cable in the small scaled electric appliances equipments. The connection of the print head and main board in various printer is very extensively now ,instrument, PLC, scanner, Auto Lamp electric appliances and various electronic equipment etc.
