TRANS-TEST is a new-technology clear plastic blank designed for use with all types of "bare board" testing machines. TRANS-TEST is available in sheets or pre-cut blanks. The blanks are drilled during the bare board testing process to manufacture translator plates. These translator plates are used to adapt the univeral grid test patterns to specific test point locations. TRANS-TEST is engineered for today's surface mount technology, SMT, boards which have densely packed test points.

TRANS-TEST competes favorably with Lexan® polycarbonate sheet or exceeds polycarbonate specifications in the following areas:
•    90% Less static charge
•    Improved flatness
•    Improved warp
•    Quick peel masking film
•    Clean and fast drilling
•    Impact resistant
TRANS-TEST is very competitively priced. Sierry Polymer Company ships all orders from stock within forty-eight hours of order receipt.
