How To Check The Quality Of Tablet Card Holder 111? What Are The Key Parameters?

4. Plating thickness: The thickness of push wire terminal block gold plating should be above 0.5 microns, and the thickness of nickel plating should be above 3 microns. Plating that is too thin is easy to wear and cause oxidation.

5. Mechanical strength: A good push in terminal block wire connector can withstand a tensile test of more than 5kg, and the terminal retention force is above 50gf.

6. Environmental adaptability: push in wire terminal block should meet the operating temperature range of -40℃ to 85℃ and work normally under 95% humidity.

7. Signal integrity: High-frequency push fit terminal block connector needs to pay attention to characteristic impedance matching, and the impedance of USB3.0 and above interfaces is required to be controlled within 90Ω±10%.

8. Dimension tolerance: The tolerance of high-quality push connector block is controlled within ±0.05mm to ensure precise docking.
