Is double sided tape conductive? What is double sided conductive aluminum foil tape used for

Ordinary double-sided tape is generally non-conductive, but it will be affected by temperature and aging.

The electronic equipment store has professional insulating double-sided tape, you can buy that with confidence.

It's easy to measure with a multimeter:

Adjust the multimeter to the current gear to select the maximum gear, and touch the two ends of the double-sided tape with the multimeter pen to see if the pointer swings.

Swinging means conducting, not moving means insulation.

Non-conductive. However, insulators have a breakdown limit, and if the voltage is high, it is still the same as conduction.

If you use it on a mobile phone, then it can be considered insulated.

But unfortunately, your double-sided tape may corrode the circuit board.

Generally, the quality of double-sided tape used by mobile phone manufacturers is very good.

It is very different from the double-sided tape in the supermarket.

But it doesn't seem to be sold on the market...

There are some types of double-sided tape on the market that are electrically conductive, which can replace the most expensive conductive tape, which I learned last time I did an SEM test in a university.

Ordinary double-sided tape is insulated, and there is no problem at all when used to glue mobile phones. If it is a conductive double-sided tape, there are two situations, infinity or close to zero, which is related to the characteristics of the conductive double-sided tape. These two types of double-sided tape are sold on a certain treasure:

How high can the voltage in the phone be?

Generally, the wire aluminum foil used as a signal line is used as a shielding to reduce the interference of external irrelevant signals to the transmission signal;

The outside is insulated for protection or leakage.

Cable foil is the use of aluminum foil airtightness and shielding, single-sided or double-sided coating plastic film, the formation of aluminum-plastic composite foil, used as the shield of the cable. The cable foil requires less oil on the surface, no holes, high mechanical properties, and the overall quality requirements are not high, but the length requirements are extremely strict.

The thermally conductive double-sided tape has good performance, which avoids the systemic risk caused by uneven paste, and the uneven heat dissipation of the light source leads to rapid light decay and dead lamp.

1. Good viscosity, in the normal use environment of the lamp, the viscosity will increase with the increase of temperature, there is no volatility, and there will be no phenomenon of thermal paste drying out and pulverization.

2. Good insulation performance, high voltage resistance 3kV, convenient for customers to pass the certification.

3. The construction is convenient, clean and fast, and the product is beautiful, reflecting the professionalism of the manufacturer.

4. No need for fasteners (screws), save the cost of screws, improve the consistency of production efficiency and finished products, save workers' man-hours, and save costs from the perspective of production management.

5 Sizes and shapes can be customized, for different LED product types, truly customized, dedicated products.

6. Convenient storage, no special environment is required to avoid curing, volatilization and hidden failure of thermal paste when environmental conditions change.

Hello First of all, single-sided conductive cloth tape:

Definition: A tape product with conductive and single-sided bonding function made of conductive textile cloth base or conductive non-woven fabric base as the base tape and coating conductive tape on one side.

Typical grades: CEF-1, CEF-2, CEF-3, CEF-3T, CEF-3B and other grades.
