Method for optics with a flex circuit test fixture

Disclosed is a method for optics with a flexible (flex) circuit test fixture. Benefits include improved throughput and improved yield.

Background

              Conventionally, the optical front-end assembly (OFE) is soldered to the printed circuit board assembly (PCBA) to test component functionality. This process is very time consuming and costly, if any of the components malfunction.

General description

              The disclosed method enables a user to screen the components quickly without soldering or using other tools. The risk of damaging the components during the soldering process is eliminated. Assembly time is significantly reduced. Yield is increased during the testing stage.

Advantages

              The disclosed method provides advantages, including:
•             Improved throughput due to reducing the manufacturing cycle time

•             Improved throughput due to minimizing optical and PCBA damage

•             Improved yield due to reducing the amount of required rework 

Detailed description

              The disclosed method includes a test fixture that enables an operator to test optical functionality without having to solder the leads to the PCB. The method screens the optics with a known good board. Additionally, it screens the PCBA with known good optics (see Figure 1).

      An operator pushes down on the handle to lift the clamp and insert the PCBA. The operator lifts the clamp to insert the OFE assembly an...
