Comparison between laser cutting and traditional cutting of circuit board cover film

Comparison of laser cutting and traditional cutting of circuit board cover film:

• Before laminating with the FPC circuit layer, the PI cover film needs to cut windows of different sizes and shapes at the 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. As circuit design gradually develops in the direction of miniaturization and high density, the traditional die-cutting method is increasingly difficult to meet the design requirements.

• Too many stamping processes will cause waste of labor costs, handling and loading and unloading time costs, quality inspection costs, etc., which will also affect the yield of the product.

  

• Picosecond laser cutting process: roll-to-roll automatic window cutting, saving time and labor, and improving efficiency and yield efficiency.

  

Cost analysis of laser cutting:

• Currently, 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 7,000 square meters/month (different products will vary). There are about 13 products per square meter, that is, the monthly production capacity is 7,000脳13=91,000 sheets/month/unit.

• Monthly output value of laser replacing traditional die-cutting technology: 9,100脳1.6=145,600 yuan/month/unit.

• Annual output value: 145600脳12=1747200 yuan/year.

• Labor cost: One person can operate the automation equipment at the same time. Calculated in two shifts, 5 equipments need 2 people to operate. Calculated based on the monthly salary of 4000 yuan

• The labor cost is about 2脳4000脳12=96000 yuan/year/5 equipments.

• Electricity cost: The current equipment power is 7000W, working 24 hours a day, the electricity fee is 1 yuan, and the electricity cost is about 61320 yuan/year.
