    • A contact tail for an electronic component useful for attachment of components using conductive adhesive, which may be lead (Pb)-free. The contact tail is stamped, providing a relatively low manufacturing cost and high precision. The contact tail has a distal portion with a large surface area per unit length. The distal portion shapes conductive adhesive into a joint, holding the adhesive adjacent the lead for a more secure joint. Additionally, the distal portion holds adhesive to the contact tail before a joint is formed, facilitating the use of an adhesive transfer process to dispense adhesive. To further aid in the transfer of adhesive, the contact tail may be formed with concave portions, which increase the volume of adhesive adhering to the contact tail. By adhering an increased but controlled amount of adhesive to the contact tail, arrays of contact tails may be simply and reliably attached to printed circuit boards and other substrates.
    • 用于电子部件的接触尾部,其可用于使用导电粘合剂附接部件,其可以是无铅(Pb)。 接触尾部被冲压,提供相对低的制造成本和高精度。 接触尾部具有每单位长度具有大的表面积的远端部分。 远端部分将导电粘合剂形成接头,将粘合剂保持在邻近引线的位置,用于更牢固的接头。 此外,远端部分在形成接头之前将粘合剂保持在接触尾部,便于使用粘合剂转移过程来分配粘合剂。 为了进一步有助于粘合剂的转移,接触尾部可以形成有凹部,其增加粘附到接触尾部的粘合剂的体积。 通过将增加但可控制的粘合剂量粘附到接触尾部,接触尾部的阵列可以简单且可靠地附接到印刷电路板和其它基底。
