Two Complementary Prototyping Paths
Depending on your stage of hardware development, we provide either zero-mold blade cutting for rapid form-and-fit validation, or 12-hour precision hard tooling for assembly line feasibility tests.
Zealinks offers comprehensive tensile strength, dielectric breakdown, and thermal aging reports for every custom die-cut prototype before mass production.

IN-HOUSE RELIABILITY LABORATORY
Three Essential Lab Tests Before Production Sign-Off
Prototypes are meaningless if they fail under real operating conditions. We provide empirical test reports to eliminate field risks before volume investment.
TEST 01 • DIMENSIONAL METROLOGY
2D Optical Measurement (Non-Contact)
Compressible materials (PORON, silicone foam, soft acrylics) deform under standard calipers. Our high-resolution 2D video measurement system uses telecentric optics to measure critical dimensions without contact.
Resolution: Up to ±0.001 mm optical scale
- Non-Contact Edge Detection: Zero physical deformation of flexible foams
- Deliverable: Full First Article Inspection (FAI) Report with 32-point dimensional mapping and CPK evaluation
TEST 02 • THERMAL STABILITY
High-Temperature Aging & Baking
Automotive sensors, battery modules, and power electronics generate high operating heat. We simulate prolonged thermal stress inside programmable chambers to inspect adhesive ooze, shrinkage, and outgassing.
Thermal Range: Ambient up to +200°C continuous soak
- Failure Modes Audited: Adhesive bleeding/ooze along die-cut edges, film curl, and carrier degradation
- Deliverable: Thermal aging curve & post-bake dimensional retention analysis
TEST 03 • BOND INTEGRITY
Adhesion Tack & 180°/90° Peel Testing
We eliminate bonding failures on target assembly surfaces (anodized aluminum, polycarbonate, glass, FR4). Testing follows ASTM D3330 and FINAT standards to quantify peel strength and release-liner pull resistance.
Standards Followed: ASTM D3330 (Peel Force), ASTM D3121 (Tack), ASTM D3654 (Shear Holding)
- Substrate Verification: Testing directly on customer-supplied production coupons
- Deliverable: Quantitative Peel Adhesion Chart (N/25mm or oz/in) & Liner Release Ratio
DFM Engineering Review & IP Protection
Before fabricating tools or cutting samples, our application engineers conduct a thorough Design for Manufacturability (DFM) audit within 2 hours of drawing receipt:
- Liner Release Differential: Ensuring tight bottom liner / easy-peel top liner to eliminate assembly line delamination.
- Extended Pull-Tab Integration: Adding zero-adhesive tabs or finger-lift edges to speed up manual operator placement.
- Adhesive Ooze Tolerance: Verifying minimum 0.3 mm clearance between internal cutouts to prevent adhesive flow onto optical lens or sensors.
- Mutual NDA Execution: We routinely sign bilateral NDAs before reviewing proprietary 2D/3D CAD models.
