Purchase DateM8 delivered 2025-06-25; partnership since 2022-11
Driving RequirementFine-pitch solder paste printing on PCBs up to 650×610mm
Mini LED production is a printing problem, not a placement problem: pads are far smaller than conventional boards, so small errors matter. For a Saudi Arabian maker, printing became the constraint.
Customer Background: Mini LED Growth in Saudi Arabia
A Saudi Arabian LED maker moved into Mini LED, where paste must land exactly on tiny pads. JHIMS’ L12 large-format solder paste printer covers panels to 1,200 × 350 mm.
Its existing printers could not reach fine-pitch alignment or handle 650×610mm PCBs. It chose the JHIMS M8 for vision, automation and reliability — delivered June 2025, extending a partnership begun in November 2022.
Project Challenges: Fine-Pitch Printing on 650×610mm Boards
- Fine-Pitch Precision Accurate solder paste application for fine-pitch Mini LED components to prevent bridging and reflow defects.
- Large-Format PCBs Handling PCBs up to 650×610mm without compromising print quality or alignment.
- Full Automation A fully automated process to reduce manual errors and operator dependence.
- Reliability & Uptime Consistent performance to meet tight deadlines and global quality standards.
Precision and large-format handling pull in opposite directions: on a 650 × 610 mm carrier, flatness, support and stencil tension vary across the panel. With fixed build dates, a stopped printer is a delivery risk.
The recorded printing challenges, the mechanism behind each, and the M8 feature that addresses it.
| Recorded challenge | Mechanism in production | How the M8 addresses it |
|---|---|---|
| Fine-pitch precision | Small apertures convert small offset errors into bridges or insufficient solder | ±0.025 mm print accuracy with ±0.001 mm repeat accuracy |
| Large-format PCBs | A 650 x 610 mm board spans more of the machine, so flatness and support vary across the panel | PCB support from 50 x 50 mm to 650 x 610 mm with stencils up to an 850 x 850 mm frame |
| Alignment on large boards | A board placed slightly off-center changes print position across the panel | CCD mark-point alignment with diagonal teaching correcting translation and rotation |
| Deposit consistency | Squeegee setting and stencil release decide how much paste transfers to each pad | Programmable print parameters recalled per product |
| Blocked apertures | Paste left in fine-pitch apertures reduces deposit volume or removes it entirely | Automatic dry, wet and vacuum stencil cleaning with spray function |
| Defect detection timing | A printing defect found after reflow costs a board and a rework cycle | Real-time 2D inspection measuring area, position offset and bridging |
| Operator variability | Manual loading, cleaning and setting changes introduce cycle-to-cycle differences | Full automation of loading, printing, inspection and cleaning |
| Uptime | A printer stop interrupts the Mini LED build schedule behind it | Pre-shipment aging tests and CPK precision checks before delivery |
| Product changeover | A new product needs a new program and new alignment teaching | Automatic program recall with mark-point teaching during commissioning |
Customer Requirements
- Fine-Pitch Accuracy The M8 solder paste printer deposits paste precisely for tightly packed Mini LED pads with no bridging.

Implementation: Deploying the M8 Solder Paste Printer
- Phase 1 — Site Survey & Planning JHIMS engineers assessed the production line, PCB portfolio and Mini LED yield targets for the M8 solder paste printer.
- Phase 2 — Configuration & Build The M8 was configured and factory-tested, including aging tests and CPK verification.
- Phase 3 — Delivery & Installation The M8 solder paste printer was shipped to Saudi Arabia, installed on-site and integrated into the existing SMT line.
- Phase 4 — Operator Training On-site training covering programming, mark-point teaching and maintenance.
- Phase 5 — Production Validation First-article validation against Mini LED yield targets before full production.
Five phases turn a printer into a qualified process, not just an installed machine — factory aging tests and CPK checks before shipment, then first-article validation on the customer’s own Mini LED product.
M8 Solder Paste Printer Customer Communication & Feedback
Communication records with the Saudi Arabian client show a seamless purchasing process and positive feedback on the M8 solder paste printer.
Configuration, schedule, documentation and training ride on correspondence — any ambiguity becomes a delay after crating. After delivery the same channel handles engineering questions without waiting for a service visit.
Video: M8 Solder Paste Printer in Action
Watch how JHIMS high-precision solder paste printers are built and what to look for in a vision printer for Mini LED lines. Watch the full guide on YouTube.
Watch the parts of the cycle that decide Mini LED yield:
- Clamping — on a 650 × 610 mm carrier, support keeps the stencil in contact across the panel.
- Vision alignment — mark-point recognition with diagonal teaching corrects translation and rotation together.
- Squeegee stroke and release — where paste transfers; a poor release leaves a ragged deposit.
- Stencil cleaning — a blocked fine-pitch aperture is the most common cause of a missing deposit.
Results: M8 Solder Paste Printer Delivers Up to 25% Efficiency Gain
The M8 delivered measurable improvements for the Saudi manufacturer:
- Efficiency Full automation shortened the production cycle and boosted efficiency by up to 25%.
- Quality The M8 solder paste printer’s precise paste application and high-precision parts reduced defect rates and improved product quality.
- Scalability Enhanced production capacity for large PCBs up to 650×610mm, serving growing Mini LED demand.
- Repeat Purchase The customer continued investing with JHIMS after the M8 — GOB line equipment and materials followed in November 2025.
Reported outcomes: up to 25% efficiency from an 8-second cycle; ±0.025 mm accuracy with ±0.001 mm repeatability and 2D inspection; boards from 50 × 50 mm to 650 × 610 mm, stencils to 850 × 850 mm.
What ±0.025 mm Accuracy and ±0.001 mm Repeatability Change on a Mini LED Line
On a Mini LED carrier, accuracy is a process gate: smaller pads make the same error bigger. Offset toward a neighbour bridges in reflow; short paste leaves too little solder. ±0.025 mm keeps deposits inside the aperture.
±0.001 mm repeatability decides whether the process runs in production rather than being sampled:
- CCD mark-point alignment with diagonal teaching corrects translation and rotation before the stroke.
- Board support and clamping hold the stencil across the 650 × 610 mm carrier.
- Automatic 3-in-1 stencil cleaning prevents the blocked apertures that cause missing deposits.
- Real-time 2D inspection on a 1.3 MP CCD measures area, offset and bridging.
