Under normal circumstances, there are two soldering methods for pogo pin connectors: reflow soldering and wave soldering.
Reflow soldering refers to brushing a kind of solder paste on the surface of the PCB board pad (contact pad), connecting one or more electronic components, and then soldering by heating in a multi-temperature reflow oven to achieve a permanent solidification joint.
Nowadays, digital electronic products are developing in the direction of ultra-small, ultra-fine and ultra-thin. The internal structure design space is becoming more and more compact, the PCB board design layout is becoming more and more compact, and the terminal products are being updated faster and faster, and the sales volume is increasing. The higher the coming, and wave soldering and hand soldering can no longer meet its development. Only by using reflow soldering technology can high-precision, high-efficiency and high-quality SMT chip production be carried out. Pogo Pin connectors are widely used in consumer electronic mobile terminals and industrial electronic products due to their small size, high lifespan, large current, beautiful appearance and convenient structural design for design engineers.
There are two ways to mount the Pogo Pin connector:
The first is the flat-bottom patch type, which is patching on the surface of the PCB board pad.
Wave soldering is the process of soldering components with molten solder forming solder waves. This soldering method requires the pins of the components to be inserted into the holes of the PCB board. Wave soldering is suitable for plug-in pin electronic components with heavier weight. Welding of very light and pinless SMD electronic components.
Rtench's drawing monograms indicate 4 types of heights, namely:
| Heights | Descriptions |
| Working height (W2) | The working height is the length from the pad to the working point. This is the drawing according to the product The recommended working height of the size and spring force parameters can obtain stable spring force and Contact resistance. |
| Max.working height (W3) | The size of the contact resistance is closely related to the size of the spring contact force (insertion force). The Pogo Pin connector needs to be pressed into a certain height to obtain a stable spring force and Contact resistance, so the Pogo Pin connector has a minimum compression requirement |
| Min.working height (W1) | Connectors have a limit compression, Min.working height is the limit compression Working height, in order to prevent crushing damage to the connector, the drawing indicates the ultimate compression The working height cannot exceed the working range of the drawing. |
| Recommended work Range (L) | Mass-produced products have tolerances. When designing products in structure, consider the patch tolerances Part tolerances and assembly assembly tolerances. The drawings indicate the recommended working stroke range, The product must be compressed to the recommended working stroke range to work in order to obtain stability Contact spring force and contact resistance. |
