Description

Clamp for LCC device manual Jin Tangxi removal Technical Field The invention belongs to the technical field of component welding, and particularly relates to a fixture for manually removing Jin Tangxi LCC devices. Background LCCs (LEADLESS CHIP CARRIER, leadless chip carriers) are a form of package for electronic components, and devices formed using such packages are commonly referred to as LCC devices, with soldered pins at the bottom and side elevation of the component, with the pins being flush with or below the bottom of the component. Because the welding process needs to perform gold-removing tin-plating operation on the pins of the component, the LCC component is small in size, light in weight and inconvenient in clamping operation, and the prior art mostly adopts a clamping mode of a clamp and other tools to remove gold-removing tin-plating, so that the component is easy to damage due to overlarge clamping force, the component is easy to fall off in the tin-plating process due to small clamping force, and the problem that Jin Tangxi is incomplete is solved. At present, a fixing mode of clamping or pressing an LCC device on a certain plane is generally adopted when removing gold and tin, so that welding operators cannot see the gold and tin removing effect of pins on the bottom surface and the side surface at the same time, the visual angle is required to be frequently adjusted or the gold and tin removing operation is inconvenient, the effect of removing Jin Tangxi is not ideal, the later welding quality is reduced, and the later welding effect is influenced.
