Why is precision dispensing required
Manual dispensing relies on operator experience, resulting in unstable glue volume, common issues such as glue accumulation, missing dispensing and stringing, and low yield consistency.
Higher Precision Requirements for Electronic ManufacturingProcesses such as PCB dispensing, component fixing and SMT patch glue repair require dispensing accuracy up to millimeter or even micron level. Manual dispensing cannot guarantee consistent glue volume, which may cause glue overflow contaminating pads or insufficient glue resulting in poor bonding. SIE‑301 delivers repeat accuracy of ±0.02mm to ensure consistent dispensing position and glue volume. Compatible with electronic‑grade materials including UV glue, red glue and solder paste, it improves yield of PCB dispensing. | Miniaturization Challenges for Semiconductor PackagingSemiconductor processes such as chip underfill, lead packaging and conductive connection impose strict requirements on dispensing accuracy and glue volume control. Small‑sized chips and limited dispensing space may cause packaging defects with slight deviations. SIE‑301 with 400×400mm working travel fits chip‑scale packaging. ±0.02mm repeat accuracy ensures precise micron‑level dispensing position, compatible with packaging materials like epoxy adhesive, silver adhesive and conductive adhesive. | Precision Bonding Demands for Medical DevicesMedical devices feature compact size and high‑precision requirements, such as micro‑component bonding, needle dispensing and catheter coating. UV glue and medical‑grade adhesives shall be applied accurately at target positions. Excessive glue impairs product functions while insufficient glue reduces bonding strength. The single‑head precise positioning mode of SIE‑301 suits micro‑component dispensing. ±0.02mm accuracy guarantees consistent dispensing quality for medical devices. |
✨ Dilemmas of traditional dispensing: Manual dispensing features low efficiency, poor consistency and unstable yield; semi‑automatic dispensers only support planar dispensing and cannot handle 3D curved surfaces; ordinary dispensers require complicated programming and long change‑over time, not suitable for multi‑variety small‑batch production.
