FPC soft circuit board terminology(2)

- Nov 03, 2018-

9, Film Adhesive Film, then sticking membrane

Refers to the following layer of dry lamination, film that can contain reinforcing fiber cloth, or the thin layer that only contains reinforcing material, such as the next layer of FPC.

10. Flexible Printed Circuit,FPC software board

It is a kind of special circuit board, which can make the shape change of three dimensional space when assembled in the downstream. Its substrate is flexible polyimide (PI) or polyester (PE).This kind of soft board is also similar to hard board, can make plated through hole or surface sticky pad, to carry out through hole insert or surface sticky.The surface of the plate can also be attached with Cover Layer for soft protective and anti-welding purposes, or printed with soft anti-welding green paint.

11. Flexural Failure deflection damage

As a result of repeated bending and bending, the material (sheet) is broken or damaged, which is called Flexural Failure.

12. Kapton polyimide soft material

This is the commercial name of dupont products, is a kind of "polyimide" thin sheet of insulating soft material. After being attached with rolled copper foil or electroplated copper foil, soft plate (FPC) can be made.

13. Membrane Switch Switch

With transparent Mylar film as the carrier, the screen printing method imprints SilverPastes (or silver paste) on the thick film line, and then matches the hollowed gasket with the protruding panel or PCB, which becomes the "touch control" switch or keyboard.This small "key" device is often used in hand-held calculators, electronic dictionaries, as well as some household appliances remote control, are called "thin film switch".

14, Polyester control-insistent pang Polyester chip

Referred to as PET chip, the most common product of dupont company, MylarFilms, is a material with good electrical resistance.Its imaging in circuit board industry dry film on the surface of the transparent protective layer, and soft board (FPC) prevent welding Coverlay is PET film surface, and it can too as silver paste printing film lines (MembraneCircuit) of the substrate, the other can also be used as a cable in the electronics industry, transformer, insulation of wire coil or more IC of tubular in such use.

15. Polyimide (PI) polyiiamide

It is a fine resin synthesized by Bismaleimide and Aromaticdiamine. It was first named Kerimid 601 powder resin product launched by Rhone Poulenc of France.Dupont made it into a sheet called Kapton.This PI board is superior in heat resistance and electrical resistance. It is an important raw material for soft board (FPC) and tape auto-bonding (TAB).

16. Reel to Reel operation

In order to save the time and labor cost of single-piece operation, some electronic parts and components, such as TAB, IC metal Frame and FPC, can be produced.
