8.2. Manufacturing and Soldering

Push the squeegee to apply the solder paste on the surface of stencil, thus making the paste fill the

stencil openings and then penetrate to the PCB. The force on the squeegee should be adjusted properly

so as to produce a clean stencil surface on a single pass. To ensure the module soldering quality, the

thickness of stencil for the module is recommended to be 0.13mm~0.15mm. For more details, please

refer to

document [5]

It is suggested that the peak reflow temperature is 238~245ºC, and the absolute maximum reflow

temperature is 245ºC. To avoid damage to the module caused by repeated heating, it is strongly

recommended that the module should be mounted after reflow soldering for the other side of PCB has

been completed. The recommended reflow soldering thermal profile (lead-free reflow soldering) and

related parameters are shown below.
