SEHO PowerSelective: For the Flexible Production with High Volumes
The most efficient and flexible machine. Dediated to high-efficiency, high-volume production. It enables to run both miniwave and dip soldering processes. It is possible to install two solder pots (for both process types).
The PowerSelective may be equipped with up to two different soldering units. Thus, miniwave soldering processes, multiwave processes and even conventional wave soldering processes can be covered with only one machine.
PowerSelective is an automated optical inspection system (AOI) that can be embedded directly in the selective soldering process. The system is used for the detection of soldering defects such as non-wetting or insufficient wetting, missing pin or bridging. The inspection begins immediately after the soldering process when the printed circuit board is fixed in the gripper of the soldering machine. The AOI system can be easily integrated into a SEHO PowerSelective, offering remarkable cost savings in relation to floor space and board handling equipment. In the field of wave soldering, SEHO will introduce two new and innovative modules. Special applications such as wave soldering with masks require selective flux application which ensures that only the points to be soldered will be wetted, not the entire mask. This avoids creepage of flux underneath the mask. Simultaneously, flux consumption will be reduced remarkably and the required cleaning cycles for the mask will be decreased. For these applications SEHO developed a coordinate fluxing unit that precisely applies the flux at the previously programmed points only. Other areas on the assembly will not be wetted.
