High-precision positioning pins/stacking pins that support the manufacturing of electronic devices.
In the electronics industry, the precise positioning of substrates and components affects product quality. Especially with the advancement of high-density mounting, even slight misalignments can lead to performance degradation or defects. Our stack pins accurately position the substrate before drilling, preventing misalignment during the assembly process. 【Usage Scenarios】 - Positioning before substrate drilling - Fixing entry boards and backup boards - Precise assembly of electronic components 【Benefits of Implementation】 - Improved assembly accuracy - Reduced defect rate - Stabilization of product quality

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. Accuracy: 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.
