Detailed Description

Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

As shown in fig. 1, the high-speed optical device with the FPC welding reinforcement structure includes a base 10 and a gold finger 110 extending from the base 10, the gold finger 110 is a ceramic gold finger with high hardness and high temperature resistance, a radio frequency FPC120 and a direct current FPC130 are welded to two sides of the gold finger 110 respectively, the radio frequency FPC120 and the direct current FPC130 extend out of the tail end of the gold finger 110, a solid reinforcement adhesive tape 140 fixed to the tail end of the gold finger 110 is disposed between the radio frequency FPC120 and the direct current FPC130, the solid reinforcement adhesive tape 140 is fixed to the tail end of the gold finger 110 by an insulating adhesive glue 150, and two sides of the solid reinforcement adhesive tape 140 are further bonded to the radio frequency FPC120 and the direct current FPC130 by the insulating adhesive glue 150 respectively, so that the solid reinforcement adhesive tape 140 and the gold finger 110, the solid reinforcement adhesive tape 140 and the radio frequency FPC120, and the solid reinforcement adhesive tape 140 and the direct current FPC130 have good insulation performance without.

Because the two sides of the solid-state reinforcement adhesive tape 140 fixed at the tail end of the golden finger 110 are respectively adhered with the radio frequency FPC120 and the direct current FPC130, the fixed positions of the two

FPCs

120 and 130 are provided with the adhesion parts with the solid-state reinforcement adhesive tape 140 except the welding surfaces, so that the fixed strength of the two

FPCs

120 and 130 is greatly enhanced, and the two

FPCs

120 and 130 and the golden finger 110 are prevented from being torn off or being in poor contact due to stress.
