PCB科技 - 柔性線路板增强板的加工效能

柔性線路板 以輕盈為特點, 薄和短, 囙此，它們也是大多數智慧電子產品的最佳選擇. 柔性電路板 也容易發生彎曲等操作, 褶皺, 使用過程中留下疤痕. 它們的機械強度低，容易開裂. 因此, 加勁肋的目的是加强 柔性線路板, 並便於在 PCB表面. 有許多類型的加强膜用於 柔性電路板. 有寵物, 圓周率, 膠粘劑, 金屬或樹脂增强板等.

1. 主要流程 柔性線路板 加强板
PCB生產 process: cutting (copper foil protective film reinforcement board PSA) - drilling (copper foil protective film reinforcement board PSA) - black holes or PTH - sticking dry film - film alignment - exposure - development - copper plating -Remove dry film-Chemical cleaning-Apply dry film-Film alignment-Exposure-Development-etch Text - Baking - Surface Treatment - PSA Pasting - Splitting - Lead Punching - Electrical Inspection - Punching Shape - FQC (Full Inspection) - OQC - Packaging - Shipment
Second, the reinforcement board fits
1. 熱壓加强板：在一定溫度下, 加强板膜的熱硬化膠開始融化, 使加强板膜粘附在產品上, 加固板定位.
2. 壓敏加固板：無加熱, 加固板可以粘在產品上.
第3, the reinforcement board is pressed together
1. 熱壓加固板：用高溫融化加固板膜的熱硬化膠, 並用適當的壓力或真空度使加强板膜緊密貼合在 柔性電路板.
2. 柔性電路板壓敏增强板：無需加熱, and the product is pressed by a cold press
Four, maturation
For the hot-pressurized reinforcing plate: the pressure during pressing is small and the time is short. 加强板的熱硬化膠未完全老化. 它需要在高溫下長時間烘烤，以使膠水完全老化，並新增加强板和產品. 附著力.
第五, 介紹 柔性電路板PCB設備
Refrigerator: store the reinforcing plate film that needs to be refrigerated
Pre-attachment machine (C/F laminating machine): laminating hot-pressurized reinforcing plate film
Manual laminating fixture: laminating cold-pressurized reinforcing plate film

80 ton fast press: laminating the finished products of PI thinner hot-compressive reinforcing plate
Cold press: press the cold-compressible reinforcing plate
Oven: Baking the finished product of the hot-pressurized reinforcing plate
Six, 柔性線路板 use fixture introduction
Pre-sticking fixture:
Location PIN:
Seven, Stiffener Film
Reinforcement board film: The mechanical strength of the reinforcement board 柔性線路板， 便於表面安裝操作. 常見厚度為5mil和9mil.
粘合劑：是一種熱固性粘合劑或壓敏粘合劑, 厚度根據客戶要求確定.
離型紙：壓前避免粘合劑粘附在异物上.
Store the reinforcing plate film that needs to be refrigerated according to the requirements on the 材料 card
Refrigeration temperature: 1~9 degree Celsius, shelf life under refrigeration conditions is 3 months
