What is UV Adhesive? Guide to UV Curing Adhesive Principle, Parameters, Selection & Common Pitfalls in Electronics Industry

2026-08-03 21:00:11

UV adhesive (ultraviolet curing adhesive) is a single-component solvent-free adhesive. It achieves cold curing within seconds under ultraviolet irradiation without damaging electronic components, and is widely applied for bonding, sealing and solder joint protection in electronic manufacturing. This article introduces its curing mechanism and core parameters (365nm curing condition, temperature resistance ranging from -55℃ to 180℃, curing shrinkage rate as low as 0.5%, etc.), and sorts out applicable scenarios including PCB protection, industrial control & new energy electronics, optical module assembly and wire harness processing. It analyzes four common misunderstandings in depth: incomplete curing in shadow areas, ignoring substrate compatibility, blindly pursuing ultra-fast curing and skipping the cleaning process. Targeted selection suggestions based on product structure, substrate materials and service environment are provided. Epoxy-modified UV adhesives with low shrinkage and excellent thermal shock resistance (such as Kimidun KM-UV305) are recommended for high-reliability application scenarios. Finally, a case of terminal encapsulation for industrial control equipment verifies the practical effect of dual-cure UV adhesive in boosting production efficiency, reducing failure rate and cutting after-sales costs....

What is the Function of PCB Conformal Coating? Essential Protection Process & Selection Guide for Industrial Control Mainboards

2026-08-02 22:52:07

Conformal coating is a polymer protective film applied on the surface of PCBA circuit boards. Its core functions include moisture resistance, mold resistance and salt spray resistance. It also provides comprehensive protection against dust, acid & alkali corrosion, electrochemical migration and delivers dielectric withstand voltage performance. It forms a dense, transparent insulating film over components and circuit traces to fundamentally eliminate mass failures such as circuit board leakage caused by moisture, copper foil oxidation and signal drift. It is a fundamental mass-production process for industrial control, new energy and outdoor electronic equipment to extend service life and reduce after-sales rework rates. Select acrylic, polyurethane or silicone conformal coating according to working conditions. Standardize construction procedures including thin uniform coating and precise masking....

Thermal Gel vs Thermal Grease Comparison | Material Selection Guide for Heat Dissipation of Power Supply & PCB Electronic Modules

2026-08-01 21:47:22

This article addresses the heat dissipation requirements of new energy power supplies, inverters, charging piles and industrial control PCB modules, and compares the core differences between thermal grease and thermal gel. Thermal grease is a paste fluid with low cost and easy application, yet prone to oil bleeding, suitable for open environments with small flat gaps. Thermal gel is a semi-solid elastomer featuring low oil bleeding and vibration resistance, which adapts to height differences between electronic components and sealed long-life modules. The article sorts out common selection misunderstandings regarding thermal conductivity selection, oil bleeding risks and hardness misconceptions. It provides standardized selection suggestions based on working conditions and reliability requirements, helping electronics manufacturers select materials reasonably and reduce product rework rates....
