Difficulty in High-precision Registration Customer Challenges： HDI, SLP, and high multilayer PCBs have high circuit density, while traditional printing equipment lacks sufficient registration accuracy, which can easily lead to pad misalignment, poor opening quality, or short-circuit risks.Technical Solution： Introduce a high-resolution CCD vision registration system, utilizing dual cameras to simultaneously recognize positioning marks and the screen, combined with a high-precision servo platform for automatic compensation and fine adjustment. Integrating a high-rigidity mechanical structure with a precision guide rail system ensures platform motion accuracy and repeatable positioning capabilityTangible Benefits： 　▲ Enhance printing registration accuracy. 　▲ Reduce circuit misalignment and short-circuit risks. 　▲Improve overall yield and process consistency2.Uneven ink film thickness affects quality Customer Challenges： Non-uniform thickness of solder mask ink or conductive paste can easily cause unstable conductivity, insufficient coverage, or appearance defects.Technical Solution： By adopting a high-rigidity printing platform and a precision squeegee pressure control system, with servo-controlled squeegee speed and printing pressure, uniform ink deposition is ensured. The printing head structure provides multi-axis fine adjustment mechanisms for squeegee angle, pressure, and depth, enabling adaptation to different ink viscosities and screen tension conditions.Tangible Benefits： 　▲ More uniform layer thickness distribution. 　▲ Improved conductivity and insulation layer quality. 　▲ Reduced rework and scrap.3. Insufficient process stability in advanced PCB manufacturing. Customer Challenges： For AI server boards and high multilayer PCB, the long process time means that if equipment precision is insufficient, prolonged production can easily result in misalignment and quality fluctuations.Technical Solution： The equipment adopts a high-rigidity welded steel structure with precision-machined reference surfaces, combined with high-accuracy linear guide rails and a servo drive system. Through stable mechanical construction and transmission design, long-term operation can still maintain positioning accuracyTangible Benefits： 　▲ Maintain stable quality during long-term mass production. 　▲Reduce process fluctuations. 　▲ Enhance reliability of advanced products4. Lengthy changeover and machine setup time Customer Challenges： In a multi-product manufacturing environment, lengthy equipment adjustment time reduces overall production line efficiency.Technical Solution： Digital process management with recipe memory enables storage of multiple printing parameter sets covering squeegee speed, pressure, platform positioning, and registration, ensuring fast changeover and consistent production quality. User-friendly HMI enables rapid operation, significantly reducing changeover and setup time to improve production efficiencyTangible Benefits： 　▲Significantly shortened changeover time. 　▲Improved equipment utilization rate. 　▲Increased production line flexibility.5. Unstable quality in micro-via hole plugging Customer Challenges： In HDI and high-density PCB micro-vias are small with high aspect ratios. If via plugging is incomplete or bubbles remain, voids can form in the holes, leading to subsequent electroplating issues and reduced circuit reliabilityTechnical Solution： By adopting high-pressure precision via plugging technology, with stable pressure control and a precise squeegee mechanism, ink is uniformly filled into micro-vias. With precise registration and a stable platform, the hole positions are ensured to fully correspond with the screen mesh openingsTangible Benefits： 　▲Improved completeness of plug-via. 　▲Reduced bubbles and void defects. 　▲Enhanced yield and product reliability in subsequent processes.6. Difficulty in double-sided solder mask registration Customer Challenges： Double-sided solder mask printing requires precise registration with pads and circuits. If registration errors are too large, it can easily cause poor pad coverage or window misplacementTechnical Solution： By introducing a high-precision CCD visual registration system, automatic recognition of positioning marks and screen alignment compensation is achieved for double-sided printing. Combined with a high-accuracy printing platform and stable pressure control, ensure printing positions precision.Tangible Benefitss： 　▲Improved solder mask registration accuracy. 　▲Reduced pad contamination and short-circuit risk. 　▲ Enhanced overall product yield.
