## **Product image** 

Similar to illustration 

High-temperature-resistant two-tier SCD-THR pin header for reflow soldering. 

- It allows you to use two interfaces on only one surface and with only one step in the work flow. 

- Outlet direction: 90° (recumbent) 

- Connections at the same level and with access that is flush over the front board. 

- Space for labelling and coding 

- Packed in cardboard box. 

Weidmüller's 3.81-mm-pitch (0.15 inch) plug-in connectors are compatible with the layouts of standard connectors and offer space for labelling and coding.

## 

Wired connection elements should be processed in accordance with the DIN EN 61760-1 standard. We have included two recommendations for practical wave soldering profiles, with which Weidmüller PCB terminals and connectors are qualified. 

- PCB thickness 

- Proportion of Cu in the layers 

- Single/double-sided assembly 

- Product range 

- Heating and cooling rates 

soldering temperature of 260°C. In practice, the maximum soldering temperature is quite often well below the above maximum profile.

**Time [sec]** 

## 

But there are more than one correct answer: The diagram of temperature-on-time is related to processing features of solder paste and to maximum load of components. 

We have to consider the following parameters: 

- Time for pre heating 

- Maximum temperature 

- Time above melting point 

- Time for cooling 

- Maximum heating rate 

- Maximum cooling rate 

prepared smoothly for the solder phase. Heating rate is typically  ≤ +3K/s. In parallel the solder paste is ‚activated’. The time above melting point of 217°C the paste gets liquid and components and boards begin to connect. The maximum temperature of 245°C to 254°C should stay between 10 and 40 seconds. In the cooling phase at ≥ -6K/s solder is cured. Board and components cool down while avoiding cold cracks.
