Stack pins (positioning pins/small diameter pins) for semiconductor manufacturing
Prevent work misalignment! Ideal stack pins (small diameter pins) for precision machining.
In the semiconductor manufacturing industry, precise positioning of substrates is a crucial factor that affects product quality. Especially in microfabrication, even slight misalignments can lead to product defects. Stack pins accurately secure the entry board and backup board during substrate drilling, preventing positional shifts. This enables high-precision processing and contributes to improved yield. 【Application Scenarios】 - Substrate drilling - Positioning of entry board and backup board - Semiconductor manufacturing processes requiring microfabrication 【Benefits of Implementation】 - Reduction of defective products due to positional shifts - Improvement in processing accuracy - Enhancement of yield

Applications/Examples of results
Before drilling the substrate, these are stack pins (positioning pins/small diameter pins) that are driven in when fixing to the entry board and backup board (bake board). The outer diameter ranges from Φ1 and the total length starts from about 8L. Chamfers can also be added to both sides of the pin. Precision: φ±0.005 (higher precision tolerances are also possible), outer diameter surface roughness can be less than Ra0.1. Material: SKH51 (HRC60 or higher), SUS materials, carbide, etc. We can manufacture from small lots, so please feel free to consult with us.
