New Crown's Four Strengths

Precision management technology that surpasses competitors and comprehensive capability to solve customer challenges

01

High Precision Management Without Variation

By processing large quantities of probe pins in batches, we minimize variation between individual units to the extreme and achieve uniform taper precision. This is our greatest technical strength.

02

High-Precision Tip Diameter Management

By precisely managing probe pin tip diameter at the micron level, we ensure reliable contact with increasingly miniaturized semiconductor pads.

03

Unique Method with Polishing Scratches Aligned with Taper

Scratches generated during the polishing process align in the same direction as the taper, increasing needle strength and dramatically improving durability. This is our unique technology not found in competitors.

04

Short Delivery Time Accelerates Development Speed

With established manufacturing processes and flexible production systems, we support short delivery time probe pin manufacturing.

Customer Benefits

Specific cost reduction and operational efficiency brought by New Crown's high-precision technology

Eliminate Incoming Inspection

Due to high-precision products, the incoming inspection process on the customer side can be omitted. Inspection costs and time can be significantly reduced.

Eliminate Sorting Operations

Since wire diameter variation is minimized through batch processing of large quantities, diameter-based sorting is unnecessary. Work efficiency is significantly improved, contributing to reduced sorting staff hours.

Reduce Unnecessary Inventory

No out-of-spec products from sorting, simplifying inventory management. Dead stock risk can be minimized.

Short Delivery Time

Short delivery time achieved through established manufacturing processes. Operation with minimum necessary inventory becomes possible, reducing inventory costs.

Practical Impact of Precision Differences

  • Measurement Reproducibility: New Crown's ±5μm precision achieves reproducibility within ±2μm even when measuring the same location multiple times
  • Defect Reduction: Precision management of tip diameter ±2μm reduces false judgments in inspection by 95%
  • Pin Lifespan: Surface roughness of 0.05μm or less achieves 3x longer lifespan compared to competitors
  • Cost Reduction: Quality assurance through 100% inspection reduces rework costs in inspection processes by 80%

New Crown's Measurement Method

Unique automated measurement system achieving high precision and high reproducibility

Features of New Crown's Measurement Method

As a specialist in mechanical polishing, we are well aware that the taper surface has fine irregularities from polishing. Since angle measurement using the surface may lack reproducibility and accuracy, we adopt a method of setting an arbitrary reference point inside the taper and automatically measuring the diameter at fixed intervals from that point. This realizes highly precise and stable measurement.

Detailed Measurement Method Diagram

New Crown Measurement Method Diagram - Arrangement from Reference Point φ15μ to Measurement Points L1-L5

Starting from reference point φ15μ, measurement points L1-L5 are set at 100μm intervals. d15 length (reference point to tip) and tip diameter are automatically measured.

Step 1

Automatic Measurement of Reference Point

Measurement Target: φ15μm (Reference Wire Diameter)

Automatically measure φ15μm as the reference wire diameter and identify its precise position. This reference point serves as the starting point for all measurements.

Step 2

Automatic Measurement of Points L1-L5

Measurement Points: L1, L2, L3, L4, L5 (every 100μm)

Set L1-L5 at positions every 100μm backward from the reference point, and automatically measure the wire diameter at each of these points.

Step 3

Tip Measurement

Measurement Target: Tip Diameter

Using the tip as reference, automatically measure the tip diameter.

Step 4

d15 Length Measurement

Measurement Target: Distance from Reference Point to Tip

Automatically measure the distance from the tip to the reference point as "d15 length".

Step 5

Taper Internal Linearity

Measurement Method: Analog Method

The linearity inside the taper is precisely measured using an analog method. Linearity faithful to design drawings is New Crown's greatest feature.

Advantages of Measurement Method

  • High Precision: Internal measurement eliminates the influence of fine surface irregularities
  • High Reproducibility: Stable measurement results through automated measurement system
  • Objectivity: Measurement method that eliminates human error
  • Traceability: Clear measurement records from the reference point
