All SMT connectors must be provided with some form of stress relief. Some connector companies use screws to lock circuit boards or accessories to panels for stress relief. While these concepts may increase mechanical strength, some solutions can provide necessary and reliable circuit board support without even secondary assembly or manual negotiation.
Through-hole reflow technology requires some form of stress relief for all SMT connectors. Some connector companies use screws to lock circuit boards or accessories to panels for stress relief. While these concepts may increase mechanical strength, some solutions can provide necessary and reliable circuit board support without even secondary assembly or manual negotiation.
Through-hole reflow technology enables surface-mount connectors to be connected through a discharger and provides more robust circuit board connections than surface-mount technology. Similar to the through pin, either the through hole reflow welding or the pin solder paste requires that the fine hole be partially drilled into the PCB, so that these fine needles can be soldered through the reflow. These through pins are used in conjunction with surface-mount signal pins, and these are often supplied with double loads through enhanced mechanical strength and grounding. However, when the through-hole reflux pin is applied to high-speed applications, there will be some disadvantages.
While surface pins are used for signal performance, through-hole reflow pins provide stronger connections on the circuit board. Moreover, with the continuous increase in the height of the interlayer connector and the weight of the sub-card, the through-hole reflow needle undoubtedly provides more outstanding stiffness and strength. As a practical standard for backboard connectors over the past 40 years, surface mount / through hole backboard solutions tend to outperform the signal performance of pressure-bonding and provide excellent durability at the same time. If the execution is correct, the surfacing technology is suitable for any application.(Printed Circuit Board Manufacturers)
