Using state-of-the-art interconnect technologies, our sales and application engineers will work with you to provide the best Test Contactors solution to meet your requirement. We supply Test Contactors solutions for both your engineering & high volume production applications.
We will take your device mechanical drawing and use Solid Works modeling software to design a custom Test Contactors to be delivered within 3-4 weeks. M Specialties LLC designs Test Contactors for all types of packages including BGA, LGA, PoP, CSP, WLCSP, QFN, MLF, QFP, SOIC, TSOP, TSSOP and MEMS. We select the best contact solution for your application from a variety of different contact technologies including 50-Gig Pillar contacts, spring probes (spring pins), elastomer, electroformed component (EFC) contacts, advanced interposers, and others.
Our CNC milling machines have a positioning accuracy of 0.0002” and repeatability of position accuracy of +/- 0.0001” which allows us to supply Test Contactors for 0.35 mm pitch devices and lower.
All of our Contactors are designed to meet or exceed your electrical testing for applications of several MHz up to 50+GHz frequencies and challenging mechanical requirements. Our high quality contacts are capable of handling leaded and lead-free packaging materials, and with minimal cleaning, can handle in excess of 500K insertions in many cases. Whether your application is RF, high current, high power, low inductance, fine pitch, low resistance, or Kelvin, M Specialties LLC has a cost effective and reliable solution for your testing needs.
We use the latest plastic materials and each Test Contactors and lid part can be easily replaced on site by the customer or by one of our local support technicians. We provide full maintenance support services at our Arizona factory in a matter of days instead of weeks.
Our high mechanical advantage lids and low profile Test Contactors are designed to reach exceptional performance levels. All of our custom designs are modeled and approved by the customer before they are manufactured, allowing you to add or request specific features to be designed into the socket or lid to accommodate load board component placement or increased air flow to the top of the IC device.
Interconnect Technologies Used by M Specialties LLC
Wide selection of spring probes (spring pins) for <=0.35 mm pitch devices and above.
Spring pins with measured bandwidth for 37 GHz at -1dB.
Reliable pins with insertions >500K cycles in most cases.
Lead free solutions:
Preserves PCB’s contact surface
Reduces cost of test
Conductive Elastomer for High speed lab testing available.
M Specialties LLC Test Contactors can handle packages as small as 1 x 1 mm to upwards of 80 mm, and with pitches from <=0.35 mm to 1.27 mm and above. Most BGA Contactors use a floating plate design to position the device before contact with the spring probes, ensure continuity, and to act as a hard stop during test to protect the pins and the package. For smaller RF, QFN, and QFP style packages that require a shorter travel pin, we can utilize a 2 plate system that uses a shelf for aligning the package. We offer a variety of hand test lid options depending on the application and engineering needs. All lids are easily removed from the Test Contactors bases for a quick change from manual to handler and back.
Lids 3 & 4 can made with an optional heat sink and/or Fan depending on the thermal requirements from the customer. And all lids are made with die probe access holes, sizes can vary based on the size of the lid and/or whether the customer wants to utilize a thermocouple in that same access hole.
Since 1999, we have been designing and manufacturing mechanical Test Contactors for our customers. We use the latest in contact technologies for engineering and final Test Contactors solutions. Our team of engineers is capable of producing a custom Test Contactors in 3-4 weeks standard lead time, with 2-3 week expedites available upon request.
