Probe tips in different styles, materials, and tip diameters, all with 20 mil or 0.508 mm shank. Probe tips are mostly supplied in boxes of 10 or 5 per box. Additionally there is the option to buy in bulk (strip of 100 tips). Low cost shipping to most countries: On payment with Moneybookers or bank transfer (minimum for bank transfer GBP 200 or $300) we can ship by Priority Mail using a flat rate box for $170 (app. 12 Euro, GBP 10.50, AUD 19, Rs850) or $150 to Canada. Since quite a lot of probe tip boxes or even 3 strips of 100 tips each will fit this box there are some savings. Just select Moneybokers (3% discount on total) and we will let you know if this shipping option is applicable for your parts selection. Recently we did intensify our relationships with various probe tip manufacturers. That allows us to offer a wider selection at lower cost. Take a look at our gold plated and solid tungsten tips. BeCu probe tips, standard Beryllium Copper or with silver plated BeCu shank. Main application is on wafers with gold metallization. Also available is gold plating in the tip area only with silver plated shank. Starting immediately all our BeCu tip packages include VCI anti corrosion paper to minimize tarnish of silver plated area and oxidization of copper tip. After trying various anti corrosion papers we did settle on Corrosorber paper.
Gold plated tips are available with a tip radius range from 2.5 to 50 µm, either completely gold plated or gold in tip area only. Most use tungsten as core material. Beryllium copper is another option with the tip only gold plated, shank is silver plated.
Solid tungsten probe tips are most commonly used for wafer probing. With aluminum pad metallization the sharper tips allow easy penetration of the oxide layer, always present on top of aluminum. Tungsten tips are available with a tip radius starting at 0.5 µm all the way up to 100 µm.
Cat Whisker probe tips use a flexible tungsten wire attached by welding, soldering, or crimping to a standard 20 mil (0.508 mm) shaft. The flexibility helps in situations with a lot of vibration present. Because of the smaller wire diameter, compared to solid tungsten’s 20 mil (0.5 mm), manufacturing an extremely small tip radius down to 0.1 µm is possible, using a relatively low cost etch process.

Custom probe tips made to order: We can supply you with special probe tips made to your specifications. Please send in your drawing or specifications for your non standard probe tip and state quantities needed. We will respond with a quote. Miniumum order quantities apply on a per design basis. Platinum plated tips: A little while ago we had a request on platinum plated probe tips - tungsten base material - with 50 µm tip radius. We did spend some effort on it but didn’t get an order. If you are interested in tips with platinum coating please drop us a note with information like base material (tungsten or BeCu), tip only or complete plating, tip radius, quantities. Please contact us with any questions. |
