Calculator repair - Adhesive conductive tape

Continuing with the repair thread we initiated 3 issues of this blog ago, we go now into the adhesive conductive tape. This is the description I get from the 3M page:

3MTM Electrically Conductive Aluminum Tape 3302 is a 2.0 mil (50 micron) high strength dead soft aluminum foil coated with specially formulated conductive pressure sensitive acrylic adhesive system. Good adhesion, malleability and adhesive conductivity allow for extremely low resistance and make this an excellent shielding tape. Designed to meet a wide variety of EMI and RFI shielding applications in the electronics industry. Also for use in printed circuit manufacture and repair.

Cut in small pieces, it can be used to cover the eroded parts of the battery contacts. Please remember to remove all oxide with Caig De-Oxit first; in some cases, the conductive film of the circuit will be destroyed in the contacting part, and there comes handy the conductive aluminium tape. You need to cover the whole contact, to maximize the electrical transfer area. Nacho thinks that it also needs to look good: a proper repairer will cover all four contacts, so that it looks coherent and symmetrical.

It also can be used in other circuits to create aground plane, and also for shielding. Every repairer should have this in his toolbox.
