Design and Configuration of 12 Pin Connector
Electrical characteristics: Balanced design of current load and contact resistance
It is recommended to control the contact resistance below 50mΩ within the rated current range of 1.0~2.0A/pin to avoid signal degradation caused by voltage drop. Use gold-plated needles with a thickness of ≥10μin to ensure low contact impedance and high reliability. Adapt to the conventional logic levels of 3.3V/5V systems.
Housing material selection: equal emphasis on temperature resistance and mechanical strength
Choose LCP or PBT +30%GF material, with a hot deformation temperature of ≥230℃. Meet the requirements of SMT/Reflow process to avoid thermal instability after assembly. The dimensional stability of the connector structure will be very high.
Contact head material and electroplating layer design
The recommended needle material is BeCu or brass, which has excellent elasticity and conductivity. The recommended thickness of electroplated gold is 10-30μin to meet the requirements of stable transmission of low voltage signals and corrosion resistance. Cooperate with nickel plating to enhance adhesion.
Layout of grounding and signal line distribution structure
To avoid crosstalk, the 12 pin connector is configured with 4 GND and the signal is isolated from the power supply. Adopting a structure of symmetrical differential + signal ground signal. It can significantly reduce crosstalk (>-30dB) and improve EMI immunity.
Design of PCB end pads and selection of fixing methods
The recommended SMD pad diameter is 0.80-2.00mm, with additional positioning posts or metal shell fixing holes. Prevent fatigue cracking of solder joints caused by shear forces during the insertion and removal process. The spacing between solder pads must meet the minimum tolerance of ± 0.05mm in PCB manufacturing.
Protection level and sealing treatment
If used for industrial or medical equipment, it is recommended to design to achieve an IP67 rating. The shell is equipped with a sealed silicone ring, and the needle seat is filled with epoxy resin. Ensure that dust and liquids cannot penetrate into the electrical contact area to improve reliability.
Electrical matching and impedance control (high-speed applications)
If used for high-speed data transmission (such as USB 3.0, LVDS), the connector impedance must be controlled within the range of<50 ± 10m Ω. Suggest using differential pair structure and simulating to verify reflection loss (S11<-15dB).
Assessment of adaptability to working environment temperature, humidity, and temperature drift
Adapt to the industrial temperature range of -40°C to+85°C, ensuring material CTE matching and avoiding virtual soldering under thermal cycling. 96 hours of high humidity aging experiment at 85°C/85% RH must be completed. Verify the performance retention of the 12 pin connector in extreme environments.
Hot swappable performance and arc suppression measures
If the application involves live plugging and unplugging, a combination of pre grounded pins (long pins) and delayed energized pins should be designed. Reserve a 3-5ms empty window to avoid arc discharge. Increasing the thickness of the gold layer to 30 μ in or above can further suppress electrical corrosion.
