Best answer

The problem of short special-shaped holes may cause some challenges in PCB processing. Here are some ways to solve the problem of short shaped holes:
1. Adjust the shape and size of the hole: By adjusting the shape and size of the hole, the effective length of the special-shaped hole can be increased, thereby avoiding the problem of short holes. For example, the inlet and outlet of the hole can be designed into different shapes to increase the effective length.
2. Add positioning holes: Adding positioning holes in PCB design can ensure the position accuracy of the PCB during processing, thereby avoiding the problem of short special-shaped holes.
3. Use accurate drilling equipment: Using accurate drilling equipment ensures accuracy and consistency in drilling, thereby avoiding short hole problems.
4. Check materials and processes: Check whether the materials and processes used meet the requirements to ensure the manufacturing quality of the PCB. For example, if thin sheet materials are used, special attention needs to be paid to preventing deviations during drilling.
5. Conduct processing tests: Before mass production, processing tests can be performed to ensure the manufacturing quality of the PCB. By observing and measuring the processed PCB, possible problems with short special-shaped holes can be found and solved.
In short, solving the problem of short special-shaped holes requires comprehensive consideration of multiple factors, including design, equipment, materials, and processes. This problem can be effectively solved by taking appropriate measures.
