Patented JJusett Lock / Rotary Fastener 

During the production process, it can quickly secure the PCB over 1mm thick to the Carrier for accepting the test or the SMT mounting. When executing the high temperature production (reflow process), it can also quickly loosen the securing point; thus, allowing the board to expand or shrink to prevent deformation.

Features：Patented eccentric circle design. Made of steel (treated with hardening and rustproof finish).
​
Advantages：

1. Secure the PCB directly without being restricted by the position of parts beside the board.
2. Prevent the PCB from deforming. Increase the production defect-free rate.
3. Easier for operation. Simple for securing and removing.
4. Allowed for repeated application. Saving the money and time. Convenient and eco-friendly.
   

​
Operation conditions：Suitable for the boards over 1mm thick.
Applicable process：Suitable for SMT printing carrier, AOI testing carrier and Fly-needle testing carrier, etc. where the board should be secured.
