Seica Offers XL Version of Flying Prober
HAVERHILL, MA — Starting with the basics and the mechan- ical designs associated with probe cards and their construc- tion, the very first constraint a user may notice is the size of the cards themselves. Traditional
tions for even larger thicknesses. One benefit of Seica’s architecture is the vertical nature of mounting the unit under test. If this were a horizontal flying probe system and as the board size/span in- creases, the weight would in-

flying probe test area sizes can be a limiting factor, so much so, the probe cards don’t even fit in the test area. To accommodate this mar-

ket requirement, Seica developed a flying prober, named the Pilot V8 XL Next>, to accommodate boards with sizes up to 32 x 27 in. (810 x 675 mm). However, the area of the board may not be the only limiting factor, as board thickness and weight are also a concern. Board construction eas- ily exceeds 50 layers in most cases, and the boards will not meet traditional thicknesses of 0.093 to 0.125 in. (2.4 x 3.2 mm). The Seica “XL” structure can
accommodate thicknesses up to standard 0.276 in. (7 mm) with op-
crease in a corresponding fashion resulting in bow and deflection of the UUT. The vertical architecture of
the Pilot V8 Next> series of testers significantly reduces the bow and deflection, allowing for faster speed and accuracy of the probing needles on the very small test points. The vertical architec- ture does not require the use of bottom side flying probe supports, or expensive jigs and shuttles that ultimately could inhibit test area for bottom side testing. With the enhanced vertical

clamping design, probe cards that exceed 15 lb (6.8 kg) have been tested in this configuration. The physical size of these probe and interface cards is not only large in some cases but their CAD data and component counts can be extensive. With very large CAD files and component counts exceeding 10,000 parts, the fly- ing probe provider needs to have the latest personal computers and robust upfront easy to use CAD processing software. The Pilot V8 XL Next> test
system uses the VIVA>NEXT> platform that is available in a 32 and 64 bit version with a new graphical interface and a guided environment for an easy and quick test program creation. It is fully integrated with NI-VISA drivers and with third-party test management software. Since the customer manages the produc- tion and material flow through the MES software, the Seica Pilot V8 XL Next> can be con- nected to the customer MES (Manufacturing Execution Sys- tem). Through its proprietary Adapter, Seica can integrate all
customer MES platforms. Contact: Seica, Inc., 110
