I would recommend trying a Board-lok Tooling support fixture. In my opinion, no other tooling support system or fixture compares to the type of support board-lok provides. They can manufacture the board-lok with many options such as vacuum, tooling p

Hi, We have several fixtures for GenRad 228x tester and would like to change sensor plates as they are quite worn. The problem is that 3 fixtures have different plate sizes for the same IC, side length is 10-12mm. What would be the best size for sens
