Comparison of laser cutting and traditional cutting process of circuit board cover film:
Before bonding with the FPC circuit layer, the PI covering film needs to cut windows of different sizes and shapes at corresponding positions according to the circuit design requirements.
The traditional manufacturing method is mainly die cutting and stamping. This process has the problems of low processing accuracy and high manufacturing cost. When the circuit design is developing towards miniaturization and high density, the traditional die cutting method is more and more difficult to meet the design requirements.
Too many stamping processes will cause waste of labor cost, time cost of loading and unloading, and inspection cost, and will also affect the yield of products.
Picosecond laser cutting process: roll to sheet automatic window cutting, saving time and effort, improving efficiency and good product efficiency.
Cost analysis of laser cutting:
At present, the die cutting cost of conventional products of large factories is about 1.60 yuan / piece. This price includes comprehensive evaluation of efficiency, production capacity, wages, molds, drilling, etc.
The current production capacity of picosecond laser window cutting is about 7000 square meters / month (different products may vary). There are about 13 products per square meter, i.e. the monthly production capacity is 7000 × 13 = 91000 pieces / month / set.
Monthly output value of laser replacing traditional die cutting technology: 9100 × 1.6 = 145600 yuan / month / set.
Annual output value: 145600 × 12 = 1747200 yuan / year.
Labor cost: one person can operate the automation equipment at the same time, and it is calculated by two shifts. Two people are required to operate the five equipment, and the monthly salary of labor is 4000 yuan
The labor cost is between 2 × four thousand × 12 = 96000 yuan / year / about 5 sets.
Electricity cost: at present, the equipment power is 7000W, working 24 hours, the electricity fee is 1 yuan, and the electricity cost is about 61320 yuan / year.
