Dispensing Protective Adhesive for Mobile Phone Battery Control Boards: Precise In-Line Coating System
Î. Why is Protective Adhesive Indispensable for Mobile Phone Battery Control Boards?
Mobile phone battery protection boards typically consist of ICs, MOSFETs, resistors, capacitors, and FPCs. Within the confined space of a mobile phone, the battery protection board faces three major threats:
Moisture and Salt Spray Corrosion:Â Â Sweat or accidental water ingress causes electrochemical migration, leading to short circuits.
Vibration and Drop Stress:Â Â Solder joints and components develop micro-cracks over long-term use.
Conductive Foreign Matter:Â Tiny metal particles from manufacturing or use can bridge circuits.
Protective adhesive ( conformal coating System  or underfill dispensing system ) forms an insulating protective layer on the component surface, effectively isolating moisture and buffering stress, reducing PCM failure rates by over 90%.
ispensing of protective adhesive for mobile phone battery control boards is no longer a simple matter of "applying it on," but rather a hig
