Alpha Probes is headquartered in the shadows of the Colorado Rocky Mountains, Colorado Springs, where all our engineers come with at least 20 years of experience within their field. No job is to small, all our probe cards are made here in America 

Planarization Test Station 

Alpha Probes uses many types of test / planarization stations for precise Z-planarity adjustment of assembled probe cards. The station can detect planarity variations in the low microns and ensures that probe card manufactured at Alpha Probes perform at the highest level of customer need. 
For probe cards with close pitch or very small bond pads, Alpha Probes always perform a probe card analysis of the card to verify alignment, planarity, leakage, Cres, overlay and other factors to ensure that the card can be immediately placed into service upon receipt.

Ceramic and metallic Blades 

Custom designed, built here in Colorado Springs. 

looking for a high frequence probe card for development  we can design and custom build you a ceramic or mettalic blade card.  A arm to custom 4" metallic blade for lazer trim, solar testing, we  also offer custom Coax probes.
