How to connect

Piezotech films can be glued to a stru影院姐姐ctural element using conductive or non影院影院-conductiveadhesives:

      ● Non-conductive adhesives are use动漫艺术d when the electrical connection i高清美丽s made directly to the piezoelectric film el大地美丽ectrodes.
      ● Conductive adhesives provide direct electr大地飘雪ical contact between the metallized sur影院姐姐faces of the piezoelectric films,好姑娘影院 and the conductive structural elements to whi直播MVch the leads have been attached. Conductive elas飘雪在线tomers can be applied to the interface of a condu国语直播ctive structural element, and the piezoelectric高清艺术 film surface to form a conducti姑娘GOve bridge.

 

In all cases however, adhesives should be c视频资源hosen among those of low polar影院MVity and havinglow dielectric constan中文版影院ts. Liquid adhesives carried by toluen动漫国语e, xylene, or aliphatic hydroc视频动漫arbons are suitable for piezoelectric 丁香花影院films. Highly polar, high dielectric-con好姑娘艺术stant adhesives such as those car好姑娘姐姐ried by acetone, ketones, and alcohol ca影院中文版n attack (dissolve) the film, and therefo视频美丽re should be avoided.
 

Acrylics, urethanes and epoxies can be s姑娘飘雪uitable nonconductive adhesives, although it is r视频姑娘ecommended to carry out beforehand, a compatibilMV中文版ity test by exposing the films to the adhe成全姐姐sive, and checking for the absence飘雪直播 of dissolution or chemical incompatibilityTV姑娘.
 

Leads can also be attached via low tem直播成全perature soldering using Ostalloy 162 Sil资源动漫ver Solder. Usually the leads should notTV艺术 be soldered directly to thin piezoelectric f免费动漫ilms (high temperature may damage the film an美丽成全d alter the piezoelectric propert视频美丽ies). Different techniques can be 美丽丁香花used:

      ● Alligator clamps-conductive rubber. Ins国语大地ulate one Jaw of two alligator clamp. Sa艺术MVndwich a small-diameter tab of con艺术TVductive rubber between the uninsulat高清版TVed jaw and the piezoelectric film. The 高清版高清版conductive rubber protects the film fr艺术影院om puncture.
      ● Solderable copper-foil tab with cond国语高清版uctive adhesive. Solder each lead to a sma高清大地ll copper foil, peel off the protective MV丁香花paper and adhere each copper tab to the piMV美丽ezoelectric film with hard finger pressure t美丽MVo assure intimate electrical contacGO免费t.
      ● Solderable copper-foil tab with 高清版TVconductive epoxy. Solder each 好姑娘动漫lead wire to a small- diameter solder美丽资源able copper-foil tab. Apply a sMV影院mall dab of conductive epoxy to 高清飘雪the underside of each copper-fo影院直播il tab. Mount the copper tabs by好姑娘好姑娘 attaching them to the piezoelectric film a姐姐姑娘nd let the epoxy cure

 

How to cut

Piezoelectric films can be cut with a razor b在线中文版lade or sharp shears or can be die-cut t影院国语o any desired dimension. Care should be taken 直播资源to prevent the edges of very th影院成全in films (6-10µm) from curling and the视频美丽reby short circuiting the top an资源飘雪d bottom electrodes. Metal fillings from the cutMV姐姐ting process can become a conductive bridg视频高清e between top and bottom metallization. LightlMV影院y brush or wipe the edges to d姐姐姐姐islodge the metal fillings.
Control the resistivity and the absenc国语视频e of short circuits between the two elec丁香花直播trodes using a voltmeter. In some cases m免费国语etal fillings can be made non-condu影院大地ctive by applying an electric 艺术美丽potential between the two sides of th大地影院e film. Metal fillings will then heat and视频影院 oxidize.
