ATE PCBs Services

Caliber Interconnects is your reliable partner for innovative design and routing solutions tailored to ATE (Automated Test Equipment) test interface boards. Our specialized team of designers works closely with your engineering experts, meticulously following your design and DFM (Design for Manufacturability) guidelines. With an unwavering commitment to delivering superior quality, we guarantee the efficient and prompt development of high-yield ATE boards.

Our Expertise

Proven Experience

Our highly experienced team has successfully collaborated with leading test board and ATE IC test system vendors, guaranteeing a deep understanding of the intricacies involved.

Signal Integrity Assurance

Each ATE board undergoes rigorous electrical analysis to guarantee optimal signal integrity. Our hand-performed signal routing takes into account critical factors like PCB stack-up, distance to reference planes, and power-to-ground configurations, meticulously minimizing crosstalk and distortion.

Specialized Designs


We specialize in crafting boards for various ATE templates, harnessing the capabilities of diverse EDA design tools to provide high-yield design solutions.

Enhanced Performance

Our designs are characterized by lower inductance and higher signal strength, translating into exceptional performance.

Load boards and Probecards for semiconductor testing

Interface boards designed to test and evaluate semiconductor devices' performance and functionality during manufacturing.


With proficiency across popular tester platforms, we have successfully managed over 10000 test board designs, ensuring quick turnarounds.



We are well-versed in working with major ATE board fab houses and specs, as well as leading probe card assembly houses.


Our remarkable capability allows us to route a staggering 40000 nets in just 2 days for memory probe cards.


We excel in designing probecards with tailored in-house signal integrity analysis capabilities.


In addition to memory probe cards, bench probecards, we excel in designing RF probe cards and load boards.
