Support post
To increase the robustness of the mechanical connection between the SKYPER
®
12 PV driver and the
corresponding board a support post could be assembled. If a support post is used, make sure it has the
correct length. A too short support post would bend both, the driver and the corresponding board that it is
mounted on, thus increasing mechanical stress. If the support post is too long, the mating connectors may
not fully support the pin header and insufficient or instable electrical and mechanical contact might occur.
The mounting hole is located in the insulation area between the secondary sides of the driver. To avoid
reduction of creepage and clearance distances when utilizing a support post, the support post’s material
must have a CTI 600 classification at least.

Solder connection
The SKYPER
®
12 PV driver core can be soldered directly onto an adapter or control board. It should be
noted that if the driver is placed too close to the adapter or control board, the clearance distances from the
driver’s primary to secondary side as well as the clearance distances between the secondary sides may be
reduced.
Soldering hints
•
The solder’s temperature must not exceed 260°C and the solder time must not exceed 10 seconds.
•
The ambient temperature must not exceed the specified maximum storage temperature of the driver.
•
The solder joints should be in accordance to IPC A 610 Revision D (or later) - Class 3 (Acceptability of
Electronic Assemblies) to ensure an optimum connection between driver core and printed circuit
board.
•
The driver is not suited for hot air, reflow or infrared reflow processes.
