Embodiment Construction

[0025] The acceptable surface deformation of the heated edge for a precision bonded thermode is typically in the range of a few microns. It is thus desirable that the thermodes used in precision bonding do not suffer from warping or other types of deformation. The thermode assemblies described herein are suitable for precision bonding without warpage or deformation issues.

[0026] figure 1 A first thermode assembly 100 is shown that may be used in a bonding process between a printed circuit and a glass substrate or other similar object.

[0027] The thermode assembly 100 has a heating element 102 which is formed at least partially from a material having a first coefficient of thermal expansion. The thermode assembly 100 also has a base 103 which also at least partially consists of a material having a second coefficient of thermal expansion which is lower than the first coefficient of thermal expansion. A tensioning mechanism is provided to tension the heating element 102 i...

Abstract

A thermode assembly comprises a heating element comprising a material having a first thermal expansion coefficient and a base comprising a material having a second thermal expansion coefficient lower than the first thermal expansion coefficient. The thermode assembly also comprises a tensioning mechanism for tensioning the heating element in contact with the base.

Description

【Technical field】 [0001] The invention relates to a thermal electrode assembly. The invention has particular, but not exclusive application to bonding objects like printed circuits to glass substrates. 【Background technique】 [0002] Conventional precision pulse thermodes are typically heating devices formed from a single piece of metal. The block of metal is shaped to form a folded blade with an elongated heating edge for heating objects in contact with it, a support structure, and a bracket for attaching the thermode to a machine, such as a robotic arm ( mount), the machine is operable to bring the thermode into contact with the object to be bonded. Current flows through the heated edge to heat it up. [0003] Applications for thermodes include bonding, for example, fine-pitch flexible printed circuits to glass substrates with similar connection points. Folded blades typically comprise a thin folded portion forming the folded portion of the heating edge and a thick blo...
