III. Material Selection Skills: No Need to Choose the Most Expensive, Just the Most Suitable

70% of the performance of a fixture depends on material selection. There is no need to blindly pursue high prices; choose according to your own products to save money and be durable. Suzhou ECLEN Electronics Technology has sorted out 4 commonly used materials for you, which are easy to understand at a glance:

1. Mainstream First Choice: Synthetic Stone (Polymer Composite Material, Must-Choose for High-Performance Scenarios)

It is high temperature resistant, dimensionally stable, and anti-static. It can withstand high temperature of 350℃ for a short time and will not deform even after long-term reflow. Its surface is smooth and does not stick to solder dross, making it easy to clean and having a long service life. It is suitable for high-precision products such as precision electronics, automotive electronics, and industrial control boards, and is also our most recommended material.

2. Cost-Effective Choice: Fiberglass Board (FR-4)

It is affordable and has sufficient temperature resistance. It is suitable for small-batch trial production and low-end electronic products (such as toys and simple control boards). For manufacturers with simple through-hole components and low requirements on precision and service life, choosing it is definitely correct, but its service life is shorter.

3. Special Scenarios: High-Performance Engineering Plastics/Aluminum Alloy

For automotive-grade and medical-grade products with extremely high requirements on temperature resistance and insulation, engineering plastics such as PEEK and PI can be selected; for large-size PCB boards, coated aluminum alloy can be selected, which is light and strong but slightly higher in cost, and can be selected on demand.

4. Auxiliary Accessories: Don’t Ignore the Details

Small accessories such as positioning pins and screws must also be made of high-temperature and corrosion-resistant stainless steel. The pressure block is made of imported bakelite to avoid scratching and rusting. Only by doing a good job in details can the service life of the fixture be longer.

IV. Design, Production + Acceptance: Do These Steps Well to Ensure Stable and Durable Fixtures

Choosing the right materials is not enough; design and production must keep up. Yikesailun’s years of standardized processes are shared with you, which are simple and easy to operate:

1. Design Key Points: Focus on Avoiding Pitfalls

• Accurate hole opening: Only open holes for through-hole component pins, and shield all other areas. Chamfer the edge of the hole and leave sufficient solder removal space to avoid bridging;

• Stable positioning: The positioning pins are precise, the PCB does not shake when placed in, and the deviation is well controlled;

• Pre-prevention: Design guide grooves in areas with high bridging risk; leave vent holes in areas with dense pins to reduce solder balls.

2. Production + Acceptance: Strict Control, No Compromise

• Precision machining: Use CNC equipment to control errors in place. Clean burrs after production to avoid scratching;

• Standard assembly: Accessories are installed firmly without loosening. Screws are countersunk to avoid sticking to solder;

• Strict acceptance: First trial-install the PCB, then conduct actual reflow testing. Rework if unqualified; mark the fixture clearly for easy management;

• Regular maintenance: Clean solder dross and flux, check the wear of accessories, and replace them in time to extend the service life.
