　　Applications: Contact microphone, Dynamic strain gages, Speakers, Switches

　　Description: The “F” in FDT Series stands for ‘Flexible Leads’. These are rectangle elements of piezo film with silver ink screen printed electrodes. Rather than making the lead attachment near the sensor, the piezo polymer tail extends from the active sensor area as flex circuit material with offset traces. This gives a very flat, flexible lead, with a connector at the end. The FDT elements are available in a variety of different sizes and thicknesses. They are available without a laminate (FDT), with a laminated (0.005” mylar) on one side (FLDT) or with tape release layer adhesive (FDT with adh) in the sensor area. The connector pins on the FDT sensors can be directly soldered to a PCB with a reasonable level of care. This component cannot withstand high temperatures (> 80°C), and therefore coldering of the pins to a PCB must be done quickly. A heatsink clamped to the interface area between the film and the crimps will take the heat away from the film. Pre-tin the pins and then quickly solder them to the board. Do not allow the soldering iron to touch the film, and do not use a dwell time of over 5 seconds on the pins. Low temperature solder can also be used.

　　Features:

　　Very flat, flexible lead
　　Available in a variety of different sizes and thicknesses
　　Available without a laminate (FDT)
　　Available with a laminated (0.005” mylar) on one side (FLDT)
　　Available with tape release layer adhesive (FDT with adh) in the sensor area
　　Connector pins on the FDT sensors can be directly soldered to a PCB with a reasonable level of care

　　典型應用: 接觸式麥克風，動態(tài)應變計，揚聲器，開關

　　產品描述:

　　"F"在FDT系列里代表“柔性引線”。FDT系列是帶銀墨絲印電極的矩形壓電薄膜元件。與其他接出引線的壓電薄膜元件不同，帶電極的壓電薄膜從動態(tài)傳感區(qū)域延伸出來作為柔性電路板，末端帶有連接頭，從而使得傳感器的引出非常扁平，而且柔軟。FDT系列有許多不同的尺寸和厚度可供選擇�？蛻艨梢赃x擇沒有聚酯基片的FDT，一面有聚酯基片（0.005”）的FLDT，或傳感區(qū)域附有雙面膠的FDT。FDT傳感器末端的插針可直接焊接到PCB。元件不能承受高溫（> 80°C），因此焊接需要迅速完成。夾在壓電薄膜和連接頭連接處的散熱器能迅速把熱量帶走。提前給插針上錫，然后迅速焊接到電路板上。不要用烙鐵接觸壓電薄膜，焊接時間也不能超過5秒鐘。可用低溫焊接。

　　特點:

　　引線扁平，柔軟
　　多種尺寸和厚度可選
　　可選無聚酯基片F(xiàn)DT
　　可選一面帶有聚酯基片（0.005“）FLDT
　　可選傳感區(qū)域帶有雙面膠的FDT
　　FDT末端插針可直接焊接到PCB
