Announcement of 2.50mm diameter Push Pins and Heat Sinks
Issue Date: 2019/04/15
new 2.5mm diameter pushpin and heat sink

Alpha has expanded its wide range of off-the-shelf products to meet customer requirements.

Alpha has added a new series of push pins, designed for use with a 2.50mm hole in the PCB. The smaller hole size will take up less PCB real estate, reducing issues related to PCB routing and conflicts. Alpha has also added a new series of heat sinks that will utilize these 2.50mm push pins for attachment.

Alpha has also added a new series of heat sinks that will utilize these 2.50mm push pins for attachment.

The new push pins will be available in 6 different lengths. The appropriate attachment force/pressure can be consistently generated through push pin/spring selection. Selection will depend on PCB thickness, chip height, package size, etc.. The simple installation process will be the same as the existing pushpins.

Initially, there will be a limited number of standard heatsinks compatible with the smaller diameter push pins. However, we will increase the number of compatible standard heatsinks in the near future.
