~ 3M#9702 (i.e. conductive tape transmission. A layer of early products) with acrylic adhesive conductive particles give a good "Z" axis (i.e. through conductive tape thickness

Degree direction) and have a high level on the X and Y axes

Impedance. Such a single or multipath connection

It's done with a piece of tape. This material is compared

New. The initial results seem to be hopeful.

It is clear that this method can be used directly to connect PCB

A plate or strip or a foil with a weld.

The disadvantage is high cost, ~1) 2) as

The material has a transmission tape.

The tendency is to stick the lining to the edge.

When the lining is removed, the "curl edge" is produced.

This product has been used in tearing lining.

The improved version (#9703) is replaced. It may not be easy to buy.

. this usually available conductive epoxy adhesive and is

Two components (glue and curing agent). Usually

A small amount of exact weighing and mixing needed

It's quite difficult. The existing products are

One component, pre mixed good material in low

The temperature is stored and used and solidified at room temperature.

Any mixture of epoxy curing usually

It is accelerated by high temperature, but due to piezoelectricity

The thin film has a mild high temperature performance.

It is usually a regular process (a lot of hours). One

The clamp is used as a clamp on the adhesive part.

Tight. Also, chaff with preweld pieces can be used

Is used to expand the contact area reasonably, to use "normal" adhesive and ultimately strengthen can be assured.

Unfavorable factors: difficult to use, long curing time, high cost, short storage time.

Low melting point alloy. Some alloys (such as indium / TiN / bismuth) rather than the flux is fusible metal at a certain temperature, melting the metal layer and the right (such as gold, copper, silver and silver ink) for piezoelectric film. Usually requires a strong corrosive welding joint may be very brittle. The mechanical strength of surface layer and the bonding metal film limit, so again, with epoxy strengthening is helpful. For small and does not require a joint high mechanical strength, this technique is useful. Only some unfavorable factors: the metallized layer is appropriate, it is difficult to sample to improve the mechanical strength is limited. (Yin Hejin).

Zebra joint ~ and production of LCD display with the same contact insulating rubber and conductive rubber. Champagne can be made of high density multi contact contact. External clamping is needed.

Mechanical fastening ~ films sandwiched between two conductive surface (a layer of conductive thin rubber) can get very good effect. The two rings can provide support for the film and loudspeaker.

Capacitive coupling, in some applications, on the piezoelectric film without metal electrode. Thin and conductive adhesive can be non metal film fixed on the conductive surface. The conductive surface actually become thin film electrode in the application. In the effective area corresponding to the sensing side of the conductive pad is PCB realization of this concept. The film on the other side of the ground electrode metal available. Available without glue or glue film is clamped between the two electrodes formed on the conductive surface.

Etched piezoelectric thin film electrode

From MSI you can buy silver ink screen printing graphic electrode can also buy vacuum sputter coating the electrode pattern, sometimes, the customer purchase full metal sheet used in the experiment, they want to make the electrode. It is difficult to screen printed silver ink, because it is not easy to corrosion and mechanical knitting. For vacuum sputtering electrode lithography the technical standard is very g
