Project 3
Project Description
Assisted in redesigning a fixture used for final quality testing of custom circuit boards. The fixture holds a row of electrical connectors in a custom 3D-printed housing designed to securely hold each connector at the appropriate location and height needed to join with it's mate on the board to be tested. The board to be tested plugs into the fixture and is held securely in place. Through the connectors, the board receives power and signals which simulate its real-world use, enabling the operator to easily ensure that the circuit board is constructed and assembled correctly.
Mechanical Design
Used SolidWorks to create a full 3D model to ensure that everything fits together well, including the mating connectors
Used SolidWorks to create a full 3D model of the circuit board, relevant connectors, the 3D-printed connector enclosures, and the plastic frame that holds the entire assembly
Used a plastic frame to reduce the risk of static discharge affecting the exposed circuit board
Electrical Design
In this case, all electronics were provided by the customer
Machining
Machined a stable frame out of three pieces of acetal resin
Rapid Prototyping
Used a 3D SolidWorks model and FDM 3D printing to quickly and easily manufacture the complicated shape of the connector enclosure
Final Product Assembly
Assembled all parts in the shop, then delivered full assembly to customer
System Validation
Worked with customer to install the fixture and test it with one of their circuit boards, ensuring it performed as desired
