Due to the continuous updating of electronic products, hard boards can no longer meet the needs of all products. The black hole production line is becoming more and more popular among engineers, but some friends are not very Know its technological process and advantages, the following editor will talk about it in detail.

I. Introduction of process flow

1. Ordinary double-sided process:

Cutting → Drilling → PTH → Plating → Pre-treatment → Pasting dry film → Aligning → Exposure → Developing → Graphic plating → Stripping → Pre-treatment → Pasting dry film → Aligning exposure → Developing → Etching → Stripping → Surface treatment → Covering film → Pressing → Curing → Immersion of nickel gold → Printing characters → Cutting → Electrical test → Punching → Final inspection → Packaging → Shipment

2. Simple one-sided process:

Cutting → Drilling → Drying Film → Alignment → Exposure → Development → Etching → Stripping → Surface Treatment → Covering Film → Pressing → Curing → Surface Treatment → Immersion Nickel Gold → Printing Characters → Cutting → Electric Testing → Punching → Final Inspection → Packaging → Shipment

Second, introduction of advantages

1. The advantage of a large flexible circuit board is that the size is relatively small, the weight is light, and the function is increased, and the cost is reduced.

2. The flexible circuit board has a high degree of flexibility, can be wired three-dimensionally, and the shape can be changed according to space constraints, and the folding and use does not affect the signal function.

3. The flexible circuit board is resistant to high and low temperature and flame resistance. And it has the properties of chemical stability and stability.

4. Flexible circuit boards are conducive to the design of related products, which can reduce errors during assembly and increase the service life of related products.

The above is "What is the process flow of the black hole production line? What are the advantages" compiled by the editor. I hope it will be helpful to everyone. If there are any unclear points, please contact our customer service to answer you.
