Getting ready for production

It's time to head for production with your new groundbreaking product. Here's some must-read information for you.

Reflow soldering specification

MiraOne is a surface mounted device (SMD) designed to be easily integrated into high-volume production lines including reflow soldering to a PCB. It is ultimately the responsibility of the customer to choose the appropriate solder paste and to ensure oven temperatures during reflow meet the requirements of the solder paste. The MiraOne module conforms to JSTD-020D1 standards for reflow temperatures.


Temperatures should not exceed the minimums or maximums presented in the table below

Lower Target Reflow Temperature 225 °C
Upper Target Reflow Temperature 250 °C
Absolute Peak Temperature 260 °C

Production Testing

All MiraOne modules are factory tested before being shipped. However, it is advised, and ultimately the responsibility of the customer, to perform some level of testing as part of your products overall test process.
