Installation requirements:
Welding temperature: Reflow peak ≤ 255 ℃, maintain above 217 ℃ for 60-90 seconds, and use insulation fixtures (temperature resistant to 120 ℃) in the positioning column area to avoid overheating and discoloration of the LCP shell (temperature resistance limit of 350 ℃, short-term tolerance).
Positioning accuracy: The tolerance between PCB through holes and positioning columns is ≤ 0.02mm. It is recommended to use a 0.01mm precision surface mount machine, and after welding, use 3D AOI to detect pin coplanarity<0.05mm.
Usage restrictions:
Non waterproof models are prohibited from being exposed to humid environments. Waterproof sealing rings are recommended to be replaced every 1000 insertions or 1 year (fluororubber, Shore hardness 70 ± 5A).
When applying 5A high current, it is necessary to ensure that the thickness of the PCB copper foil is ≥ 50 μ m (1.4oz), the VBUS wire width is ≥ 1.5mm, and a 100nF X7R ceramic capacitor (≤ 5mm from the interface) is connected in parallel to suppress high-frequency ripple.
Compatibility Description:
The third mock examination protocol requires device side chip support (such as Ruiyu RTS5490). It is recommended to use USB-IF certified 40Gbps EMarker cables (such as USB4 Gen3, AWG28). Non certified cables may cause PD handshake failure or data packet loss.
Maintenance suggestion:
Clean the interface dust with compressed air (0.5MPa) every quarter in industrial environments, and wipe medical equipment with 75% ethanol (chlorine containing disinfectants are prohibited) to avoid contact between LCP shells and strong acids and bases (customized protective coatings are required for pH values outside 5-9).
When idle for a long time, use LCP dust cover (sealed in static shielding bag), store at a temperature of -20 ℃ to 60 ℃, humidity ≤ 40% RH, and keep away from strong magnetic fields (>50mT) to prevent brass terminals from magnetizing.
