Atonm Magnetic Grid Readhead Application Case on Chip Mounters

I. Customer Background

The customer is mainly engaged in the production of electronic manufacturing equipment, and its chip mounters are widely used in various electronic product production workshops. With the increasing refinement of electronic products and the rising requirements for production efficiency, the precision and speed of the existing positioning and transmission systems of chip mounters can no longer meet production needs and are in urgent need of upgrading. During the operation of chip mounters, accurately positioning component positions and achieving high-speed and stable operation are crucial to ensuring product quality and improving production efficiency.

II. Pain Points of the Customer's Existing Products and Solutions

Insufficient Precision

The original positioning system struggles to meet high-precision requirements. When mounting tiny electronic components, position deviations often occur, leading to an increased product defect rate. For example, for some chips with extremely small pin pitches, poor pin soldering frequently happens due to positioning errors, which seriously affects product performance and qualification rates.

Speed Limitations

The equipment operating speed cannot keep up with the pace of large-scale production. When attempting to increase mounting speed, the stability of the original system drops sharply, resulting in freezes and jitters. This not only impairs mounting precision but also easily causes equipment failures and frequent downtime for maintenance, which greatly reduces production efficiency and increases production costs.

Stroke Restrictions

The existing positioning components have a limited stroke range, which cannot meet the ever-expanding working area requirements of chip mounters. When mounting components on some large-size circuit boards, it is impossible to achieve comprehensive and efficient mounting operations, which limits the application scope and production flexibility of the chip mounters.

III. Solution

The Atonm Magnetic Grid Readhead MH0-H200D-L06-0001 paired with the Magnetic Scale MB200 was introduced. The Atonm Magnetic Grid Readhead MH0-H200D-L06-0001 boasts outstanding performance advantages:

Its magnetic grid repeatability accuracy reaches 5 μm, which can accurately capture position changes during the movement of the chip mounter, providing precise position feedback for the mounter and ensuring electronic components are accurately mounted at designated positions on the circuit board.

Meanwhile, the readhead can adapt to a maximum operating speed of 2 m/s, maintaining stable data reading and transmission even under high-speed operation, thus guaranteeing the positioning accuracy and stability of the chip mounter during rapid operation.

The matched Magnetic Scale MB200 has a customizable length, meeting the stroke requirements of 600–800 mm. This effectively expands the working range of the chip mounter, enabling it to easily handle mounting tasks for circuit boards of different sizes.

In terms of installation, the Atonm magnetic grid system features a compact design, making it easy to integrate into the existing structure of the chip mounter without requiring large-scale modifications to the equipment. This reduces installation and commissioning time and costs.

IV. Customer Benefits

Improved Product Quality

The high-precision positioning function of the Atonm Magnetic Grid effectively reduces the position deviation of electronic component mounting, drastically minimizing the number of defective products caused by mounting errors. The product qualification rate has been significantly increased, enhancing the competitiveness of the customer’s products in the market. Meanwhile, it reduces after-sales costs and reputation losses arising from product quality issues.

Enhanced Production Efficiency

The high-speed adaptability of the magnetic grid readhead enables chip mounters to greatly increase mounting speed while maintaining high precision. Previously, only a certain number of mounting tasks could be completed per hour; now, with the speed upgrade, the number of mountings per unit time has increased. This meets the customer’s growing order demand, shortens product delivery cycles, and strengthens the customer’s market responsiveness and competitiveness.

Expanded Equipment Application Scope

The customizable stroke length of the Magnetic Scale MB200 allows chip mounters to handle mounting tasks for larger-sized circuit boards. No longer restricted by circuit board dimensions, the customer can undertake more diverse types of electronic manufacturing orders, effectively expanding their business scope and creating potential market share and business opportunities.

Reduced Comprehensive Costs

On one hand, improved product quality reduces raw material waste and rework costs caused by defective products. On the other hand, higher production efficiency lowers the per-unit product allocation of costs such as equipment depreciation and labor. In addition, enhanced equipment stability reduces maintenance costs and production stagnation losses due to fault downtime, cutting the customer’s comprehensive production costs in multiple aspects and improving the enterprise’s economic benefits.

Upgraded Equipment Intelligence Level

The Atonm Magnetic Grid system provides more accurate and real-time position data feedback for chip mounters, facilitating the mounter control system to achieve more intelligent motion control and production management. Through integration with other automated equipment, the entire production process can be further optimized, upgrading the automation and intelligence level of the production workshop and laying a foundation for the customer’s future industrial upgrading and technological innovation.
