Finding the ECT Equivalent to an Existing Spring Probe Solution

Everett Charles Technologies Introduces the new online part conversion tool

Everett Charles Technologies (ECT) has recently launched a new online parts conversion tool, which converts most industry or competitors’ part numbers to a functionally equivalent ECT solution.

ECT has implemented a new online tool to convert non-ECT spring probe part numbers into ECT equivalent part numbers. The new cross-reference tool provides customers with a quick and easy way of determining if an ECT equivalent probe is available for their application.

When a customer enters a competitor’s part number into the cross-reference tool, it will provide an exact match to an existing ECT part number if available or to a “functional” equivalent when a perfect match does not exist. The conversion result includes a link to the product page on the ECT website, where detailed specifications allow customers to engage in more in-depth analysis of the ECT alternative. This lets the customer instantly check the electrical and mechanical specification of ECT’s recommended probe match and to compare critical parameters to verify compatibility.

Tony DeRosa, Product Manager, explains: “Our proficient engineers compiled the data for this tool, which leverages ECT’s extensive knowledge of spring probes along with our applications experience to allow us to accurately recommend conversion to ECT probes.”

ECT’s BTP/BTLP Series Supports Bead Probe Testing of PCBs

Leveraging ECT’s Expertise and Innovation for this Advanced PCB Test Approach

Everett Charles Technologies (ECT) has developed a series of spring probes, BTP and BPLT, specifically for bead probe test. Combining well-established design and plating principles with an innovative tip design to fully support the special requirements for contacting bead probes.

Spring probes used for bead probe test must be capable of reliable and repeatable positional accuracy to contact the hemi-ellipsoid target shape. Since bead probe structures are sensitive to contamination from solder and other materials, the test probe tip geometry must be sharp to minimize transfer.  Sharp tips also allow for lower spring force probes which can increase mechanical reliability of the test fixture.

ECT has developed an innovative flat and “micro-textured” tip that is optimized for contact to the hemi-ellipsoid shape of bead probes as small as 0.004”.  The textured surface is formed by closely spaced triangular pyramid shapes.  This geometry ensures highly accurate contact of the typical bead probe which is long, but also small in width when placed on a PCB trace.

ECT’s BTP and BTLP probe series leverage the proprietary POGO Plus® design applying the bias ball technology to maintain an excellent internal contact between the barrel and plunger even at the low forces required for bead probe applications.

ECT’s LFRE plating, which is a proven solution for lead-free contacting based on its extreme hardness of 550 to 650 Knoop, ensures a less porous and more durable surface that is less susceptible to solder and material transfer from bead probes.

Tony DeRosa, Product Manager, explains: “With the BTP/BTLP probe series, ECT enables our PCB Test customers applying bead probe technology to significantly improve their first pass yield in high volume applications. We support this technology with OEM’s, contract manufacturers, and test fixture partners.

Choosing the Right ECT Spring Probe for ICT and FCT Testing

How do I select Base Material / Plating, Spring Force, and Tip Selection?

In the world of spring probes, choices abound when it comes to selecting materials and platings for plungers, barrels and springs. Choosing the right options can greatly impact yield, probe life and cleaning frequency.

Base Materials

BeCu is a popular choice for both plungers and barrels and has outstanding mechanical properties with high electrical conductivity. Steel is significantly harder and is typically used for plungers with aggressive tip styles. Nickel Silver is very resistant to corrosion and is well suited for barrels. Bronze has good wear resistance, cold formability and high electrical conductivity. Lastly, brass is a high quality material with high electrical conductivity and good wear resistance.

Plating Choices

Choosing the right plating depends on the application and customer preference.  Gold is widely used and provides excellent electrical performance and good corrosion resistance. To address lead free solder challenges, ECT has developed a proprietary plating material called LFRE which is approximately 5 times harder than gold.  LFRE plated tips are much more durable and wear resistive than gold and have proven to last more than twice as long as gold plated probes. LFRE probes are also less susceptible to solder and material transfer and require less cleaning than gold plated probes.

Spring Force

Spring force selection is mainly dependent upon the application. It provides the required compliant force at the plunger tip and the contact force between the barrel and the plunger. Higher spring forces provide more effective penetration through contamination contact points, but leave heavier witness marks on the test point. Lower spring forces should be used where no witness marks are welcome or to prevent board flexing on higher pin count applications.  Stainless steel must be used for springs when test temperatures exceed 100°C.

Tip Selection

Most tip styles can be used for a variety of different applications. However, some test targets are better suited for unique tip styles. Some applications require a non-aggressive tip to be used on pads, such as radius, crown, or flat.  These tips leave little to no witness marks on test pads. For through-hole vias ECT offers: blade, star, or pyramid tip styles. These are well suited for contact through the outer ring of the via surface. Over time solder builds up oxide layers, therefore medium to very aggressive tips like the serrated, crown, blade, pyramid and point are used. Posts, pins or screws are more unpredictable and therefore more challenging. For these applications, tip styles like the cup, serrated and crown are best suited. Other applications may require more unique tip styles depending on test target material, size, shape, access and cleanliness.   With over 50 years of making high quality spring probes, ECT has developed a vast library of probe options for all your testing needs.

Everett Charles Technologies Non Magnetic

Probes for Reliable Sensor Testing with Full Temperature Range

Everett Charles Technologies (ECT) expands its product portfolio with non-magnetic spring probes for test applications, which are based on the measurement of the earth′s magnetic field in the full ambient/hot/cold temperature range. ECT non-magnetic probes ensure accurate, reliable and repeatable measurement of the earth′s magnetic field and the yaw rate movement in any of the three axes without interference from the test probes.

ECT′s non-magnetic probes support typical navigation applications in smart phones or dedicated navigation devices for cars in the fast growing MEMS/sensor market. For the development of these probes ECT not only drew upon its long-term experience in spring probes and materials, but also the comprehensive expertise within Xcerra in MEMS/sensor testing. By combining these elements ECT is able to provide non-magnetic spring probes that meet the challenging requirements of tri-temp MEMS/sensor testing. Sensors that measure the earth′s magnetic field and the yaw rate movement must be tested in a benign environment. To test sensors reliably without interference from the test stimulus, any possible materials that might disturb the earth′s magnetic field are not allowed in the area around the device under test. In addition, since many applications are bound for the automotive market, the test probes need to withstand temperature of -55°C up to +85°C and in some cases up to 150°C.

Tony DeRosa, Product Manager, explains: “By leveraging off of the vast sensor test experience within Xcerra, we are able to develop non-magnetic spring probe solutions with extraordinary performance in an unmatched temperature range. Our non-magnetic probes have been already deployed in volume production, where the outstanding performance has been confirmed.”
