In electronic product manufacturing, cutting and punching are usually two consecutive processes. For example, for Flexible Printed Circuits (FPC), the outer profile needs to be cut first, followed by the punching of positioning holes and vias; for sensor housings, the contour needs to be cut out first, then mounting holes and ventilation holes are punched; even for some metal shielding covers, both edge trimming and heat dissipation hole punching are required.

The traditional approach is to purchase a separate cutting machine and a punching machine, or use one piece of equipment to process the workpiece in two separate runs. However, this not only takes up extra floor space, but also adds time for loading, unloading and work-in-progress transfer.

Jiajiayong Laser has focused on precision laser processing for 29 years. Today, we would like to discuss how the integrated cutting and punching solution is realized, and how much cost it can save for your business.

I. Why do electronic products need integrated "cutting + punching" solutions?

In the manufacturing process of electronic products, cutting and punching operations are often required for the same component. Take FPC as an example: it is necessary to first cut the profile along the board edge, and then punch holes at designated positions. If cutting and punching are performed separately, two pieces of equipment are required, or the same equipment needs to have its fixture changed twice, with repositioning required in between. This not only wastes time, but also tends to cause cumulative errors due to secondary positioning.

The core value of the integrated solution lies in completing all processes with a single clamping. After the workpiece is placed on the equipment, the equipment automatically identifies its position, cuts the outer profile first, then moves to the specified coordinates for punching, with no manual intervention required throughout the process. This reduces transfer time and avoids errors caused by repeated positioning.

II. Technical difficulty: different parameter requirements for cutting and punching

• · For cutting: A relatively large light spot (usually 0.1-0.3mm) and relatively high power are required, with oxygen or nitrogen used to blow away the molten material, ensuring a narrow kerf and smooth edges.

• · For punching: An extremely small light spot (minimum 3μm) and precise energy control are required to avoid an excessively large heat-affected zone and ensure burr-free hole walls.

If one piece of equipment is to perform both tasks well, it must have the capability to switch parameters rapidly. Jiajiayong Laser's integrated equipment adopts a dual-mode optical system: the large-spot galvanometer is used in cutting mode, and the system automatically switches to the high-power focusing module in punching mode, with a switching time of no more than 1 second. Meanwhile, the software has built-in independent parameter libraries for cutting and punching. The operator only needs to select "cut first, punch later" or "punch first, cut later", and the system will automatically call the corresponding energy, speed, focus and gas parameters.

III. Practical application scenarios: Which electronic products benefit the most?

• · FPC flexible circuit boards: Cut the outer profile first, then punch positioning holes and pad holes. The integrated solution combines the two processes, increasing the takt time by 40% and avoiding secondary positioning deviations.

• · Metal shielding covers/heat sinks: First cut the contour with laser, then punch arrayed heat dissipation holes. Traditional stamping molds have high costs and slow changeover speeds, while the laser integrated solution requires no molds and can process materials as soon as the drawing is provided.

• · Sensor housings: First cut out the mounting surface and window, then punch lead holes and ventilation holes. The process is completed with a single clamping, ensuring the relative position accuracy of all features.

• · Plastic/acrylic panels: Cut the panel profile first, then punch indicator light holes and key holes. The edges are smooth and burr-free, eliminating the need for secondary grinding.

IV. Economic benefits: How much money can the multi-purpose machine save?

Take a medium-sized FPC foundry with a monthly output of 100,000 FPC pieces as an example, each piece requiring profile cutting and 8 holes punched.

• · Split solution: One cutting machine (200,000 RMB) + one punching machine (300,000 RMB), occupying 8 square meters, requiring 2 operators. The loading, unloading and transfer time increases by 15 seconds per piece, with an extra monthly labor cost of approximately 15,000 RMB.

• · Integrated solution: One piece of equipment (400,000 RMB), occupying 4 square meters, requiring 1 operator, with no transfer needed. The monthly labor cost is reduced by 15,000 RMB, and the yield rate is increased by 2% (due to the elimination of one positioning error).

Three-year total cost comparison: The split solution costs approximately 1.2 million RMB (equipment + labor + floor space), while the integrated solution costs approximately 800,000 RMB, saving 400,000 RMB. In addition, the integrated equipment can take on more types of orders, offering higher flexibility.

V. Capabilities of Jiajiayong Laser's integrated equipment

Jiajiayong Laser has focused on precision laser processing for 29 years. Our integrated cutting and punching equipment has the following features:

• · Dual-mode fast switching: The cutting mode has an adjustable spot size of 0.1-0.5mm, the punching mode has a minimum spot size of 3μm, and the switching time is less than 1 second.

• · High-precision visual positioning: The CCD automatically identifies the Mark points on the workpiece to compensate for incoming material deviations, and the position accuracy of both cutting and punching is controlled within ±5μm.

• · Intelligent process database: It has built-in cutting and punching parameters for more than 200 materials (FPC, PI, stainless steel, aluminum alloy, acrylic, ceramic, etc.), which can be called with one click.

• · Automation integration: It can be equipped with automatic loading and unloading, assembly line docking, and MES data traceability to realize unattended production.

• · Multi-purpose machine: In addition to cutting and punching, it can also be equipped with a marking function, allowing one piece of equipment to complete three processes.

VI. Suggestions for you: Send samples first to verify the effect

Whether the integrated cutting and punching solution is suitable for your products depends on the material thickness, hole complexity and batch size. The most reliable method is to send a batch of typical workpieces and drawings. Jiajiayong Laser's application verification center will complete the sample production within 3-5 working days, and issue a detailed report including cutting edge quality, aperture CPK, takt time estimation and investment return analysis. If you are satisfied with the result, we can further discuss the solution in depth; if not, you will at least have obtained professional data, which will be a reference for your subsequent decision-making.

Over the past 29 years, Jiajiayong Laser's tenet has remained unchanged: to make no hole difficult to drill and no edge difficult to cut in the world. We will work with you to think through the integrated solution thoroughly and implement it properly.
