In order to adapt to complex space environment, the on-resistance value of the solar cell array substrate and part of honeycomb sandwich structure plate is generally required to be not more than 200-1000 omega.

The structural adhesive and the foaming adhesive are all insulating materials, so that the phenomena of insulation or overlarge resistance value can be generated due to the fact that the metal embedded part and the honeycomb sandwich structure main body (honeycomb core lattice and panel) are completely isolated by the adhesive.
The traditional honeycomb sandwich structure uses conductive adhesive to conduct loop treatment on poorly conducted or insulated embedded parts, the conductive adhesive is prepared by using silver powder as a filler and resin, unstable phenomenon exists, the conductive adhesive is qualified when the conducting loop treatment is just finished, the resistance value becomes large after the adhesive is solidified, and the conductive adhesive exceeds the design requirement value and needs to conduct treatment again. After the product is stored for a long time, transported or subjected to a thermal test, the phenomenon that the resistance value exceeds the design requirement also occurs frequently, mainly because the conductive adhesive is in adhesion-contact connection, any contact surface changes, such as aging, virtual adhesion and cracks, can cause the resistance value to change, and the storage environment changes, transportation vibration and thermal expansion and contraction can cause the contact surface to change. At present, the conductivity of the embedded part after the adhesive bonding molding in the traditional process is less than 30%, and the repairing proportion after delivery reaches 20%.
