Driving RequirementConsistent print quality for mixed-product batches at scale
Mixed-batch OEM work means many different products and moderate volumes, with quality judged on consistency, so the printing step must be repeatable rather than fast. Long tuning per new article costs the line.
Customer Background: Scaling OEM Production
The Indian client, an OEM product manufacturer, faced order volumes its line could not absorb. It chose the JHIMS L5 solder paste printer from Shenzhen Jinghe Technology Co., Ltd. for precision and cost-effectiveness.
A dependable L5 printer makes print consistency the base of placement and reflow quality, via automatic squeegee pressure control. JHIMS also offers L12 for large panels, up to 1,200 × 350 mm with 2D paste inspection.
Unlike manual or semi-automatic printers, the L5 loads, prints and transports boards automatically. Its compact footprint fit the client’s layout, and the 220 V supply matched Indian industrial power.
Project Challenges
- High-Precision Manufacturing Meet high-precision requirements across multiple OEM product types.
- Process Optimization Optimize the production process and reduce workforce dependency.
- Lower Operating Costs Reduce operational costs while maintaining quality.
- Staff Turnover Protection New operators must be able to learn the machine quickly without interrupting production.
- Data Protection Backup systems and programming software data backups to prevent data loss.
- Space & Power Constraints The machine must fit an existing factory layout and run on standard Indian 220V industrial supply.
Three pressures arrive together as OEM order volumes grow: precision for the hardest board in the mix, repeatability without a skilled operator watching, and lower cost per board rather than more people at the printer.
The reported pressures on the printing step, and how the L5 configuration addresses each.
| Reported challenge | What it costs in production | How it is addressed |
|---|---|---|
| High-precision manufacturing | Qualification per product type, risk of defects on fine pitch | ±0.025 mm accuracy, ±0.01 mm repeatability |
| Process optimisation | Operator-dependent results, variability between shifts | Vision-aligned printing instead of manual alignment |
| Workforce dependency | Additional volume requires additional operators | Automated loading, printing and transport |
| Quality assurance | Defects found after reflow are expensive to correct | Integrated 2D inspection in the same cycle |
| Mixed order book | Long setup per product, low printer utilisation | Program-based product changeover, sub-7-second cycle |
| Operating cost | Flat cost per board as volume grows | Fewer operators and less rework per board |
Customer Requirements
Before purchasing, the client verified that the L5 could meet five non-negotiable requirements for OEM production:

The L5 solder paste printer became the cornerstone of the client’s printing process — a high-cost-performance machine built for OEM scale.
The customer reported improved production efficiency and print consistency, fewer manual operations, lower costs after the L5: vision alignment holds ±0.025 mm, and 2D inspection catches defects before reflow.
What ±0.025 mm Print Accuracy Means on the Line
A print accuracy figure needs context. ±0.025 mm is twenty-five micrometres, about a quarter of the width of a human hair. Repeatability of ±0.01 mm matters in volume: it shows how much the result moves between boards.
At fine pitch the figure becomes visible: smaller apertures and paste volumes turn a small error into bridging or insufficient solder — hence the 0.4 mm pitch BGA requirement, which sets the mix one printer can cover.
