FAQs:
Q: In which specific areas of the electronics industry is this
solid pencil needle primarily used?
A: It is highly suitable for high-density electronic test fixtures (such as ICT/FCT), micro-hole
cleaning in PCB boards, semiconductor wafer probe testing, precise
positioning in BGA rework, as well as the precision picking and
assembly of miniature electronic components. Its solid and sharp characteristics make it an ideal choice for
scenarios requiring extremely high penetration precision and minimal contact area.
Q: What is the minimum diameter available for the needle tip, and
how is the precision guaranteed?
A: With our standard process, the needle tip diameter can be customized down to the 10-micrometer (μm) level. By utilizing ultra-fine micro-machining and Wire Electrical Discharge Machining
(WEDM) technology, combined with subsequent precision optical grinding, we ensure the tip possesses extremely high concentricity (Runout < 0.005mm) and straightness. This means the tip will not wobble during high-speed contact with
the workpiece, ensuring every contact precisely lands on the target
pad or test point.
Q: How is the durability of this needle for high-frequency
automated testing?
A: Benefiting from the application of special cemented carbide or high-hardness steel, as well as high-wear-resistant surface treatment processes, this pencil needle exhibits excellent resistance to wear and fatigue. In a standard automated ICT testing environment, its service life
far exceeds that of ordinary High-Speed Steel (HSS) needles,
effectively reducing the frequency of probe replacements due to increased
contact resistance caused by tip wear, thereby lowering your overall maintenance costs and increasing
production capacity.
Q: If our test probes require contact with very small areas, can
you provide customization services?
A: Yes, we offer comprehensive non-standard customization services. Based on your CAD drawings or samples, we can customize different shaft lengths, specific tip tapers (e.g., 10°,
15°, 20°, etc.), and different handle/interface shapes. As long as you provide specific tolerance requirements and test
parameters, our engineering team will evaluate and provide the
optimal manufacturing solution to ensure the product perfectly fits
your equipment.
