The prospect of flexible circuit board
In the next few years, smaller, more complex and more expensive assembly of flexible circuits will require more novel methods of assembly, and the need to increase the hybrid flexible circuit. The challenge for the flexible circuit industry is to keep pace with the computer, telecommunications, consumer demand and active market. In addition, the flexible circuit will play an important role in the lead-free operation.
Because of the addition process and the low cost of the base material, the polymer thick film circuit is 1/10 of the price of the copper polyimide film circuit; the price of the rigid circuit board is 1/2 ~ 1/3. Polymer thick film method is especially suitable for equipment control panel. In mobile phones and other portable products, the polymer thick film method is suitable for converting components, switches and lighting devices on the printed circuit board into a polymer thick film circuit. It can save cost and reduce energy consumption.
Its representative flexible substrate is PET. Polymer thick film conductor including screen printing metal filler or carbon filler. Polymer thick film method itself is very clean, use lead-free SMT adhesive, without etching.
Flexible circuit industry is in a small but rapid development. Polymer thick film method is an efficient and low cost production process. In this process, on the cheap flexible substrate, the selective screen printed conductive polymer ink.
