Haptic Feedback Transfer Pad — Premium Notebook Touch Panel
Background & Challenge
A premium Notebook integrated haptic feedback into its Touch panel to enhance the human-machine interaction experience. The quality of the haptic effect critically depended on precise mechanical transfer control — too strong resulted in jarring vibrations, too weak left users barely perceiving feedback. After multiple unsuccessful adjustment attempts, the customer urgently needed a purpose-built adhesive pad solution capable of precisely meeting haptic transfer requirements.
LSIGHT Solution
Through multiple rounds of technical discussions with the customer, LSIGHT leveraged 16 years of die-cutting expertise and strong technical development capabilities to perform reverse analysis on the haptic transfer mechanical curve. We developed a purpose-built haptic transfer adhesive pad, achieving precise control of pad thickness and hardness through precision die-cutting processes to deliver full yet smooth mechanical feedback.
Results
The product met all R&D target specifications. Haptic feedback intensity was well-balanced with clear, natural user perception. Successfully entered mass production and was shipped.
Thermoplastic Bonding Film — PC Panel to PCBA Bonding
Background & Challenge
The original PC panel-to-PCBA bonding used a 3M double-sided tape solution. While performing well in bond strength and environmental testing, it showed a significant weakness in bending resistance — bending deviation reached ±0.5mm, affecting overall structural flatness and assembly yield. The customer sought an alternative that maintained bond strength while substantially improving bending resistance.
LSIGHT Solution
LSIGHT developed a purpose-built thermoplastic bonding film to address the bending resistance requirement. The material forms a stable structural layer after heat-activated bonding, effectively suppressing panel bending deformation. Precision die-cutting ensured high-accuracy fit with both the PC panel and PCBA board.
Results
Bending deviation reduced from ±0.5mm to ±0.2mm — a 60% improvement. Bond strength and environmental test performance exceeded the original 3M solution, earning strong customer recognition.
Aerospace-Grade Weather & Chemical Resistant Nameplate — COMAC C919 Lavatory
Background & Challenge
During development of the C919 lavatory nameplates, COMAC imposed exceptionally stringent material requirements: the nameplates needed to maintain color stability, firm adhesion, and appearance integrity under prolonged UV exposure, extreme temperature/humidity fluctuations, and repeated wiping with aviation cleaning agents — simultaneously meeting both high weatherability and chemical resistance. Multiple rounds of prior sample submissions had failed to satisfy both design criteria.
LSIGHT Solution
Drawing on years of electronics materials experience, LSIGHT designed a systematic solution encompassing substrate selection, surface weathering coating, and chemical-resistant adhesive systems. Precision die-cutting achieved exact dimensional and structural accuracy. Our team worked closely with the customer, rapidly iterating prototypes to overcome weatherability and chemical resistance bottlenecks one by one.
Results
The project progressed from concept to full validation in under 2 months through just 3 sample iterations. With aerospace-grade high-reliability quality, this project once again demonstrated LSIGHT's technical strength in high-weatherability, high-chemical-resistance material die-cutting.
