ViaSampling System

ViaSampling System

High-precision coupon extraction and preparation in a few, simple steps

ViaSampling System

  • Custom-designed for the Printed Circuit Boards (PCB) industry
  • Representative samples from most board types, rigid and flex
  • Guaranteed, repeatable results – no lost samples
  • High-precision preparation of microvias down to 100 μm
  • System precision better than ± 20 μm
  • Minimum preparation costs
  • Continuous routing feature for highest productivity

The Struers ViaSampling System consists of two parts: ViaSampler ViaSampler is a dedicated, fully automatic coupon extraction station with a precision router-cutter (milling tool) for drilling two positioning holes anywhere on the board and extracting 10 x 20 mm test coupons. ViaKit ViaKit is a toolkit that includes all you need for pinning, mounting, and preparing coupons, making your coupon preparation process much easier. It is designed for high-precision preparation of up to 36 coupons at a time and is used along with ViaSampler. An entry-level version of ViaKit is also available.



High precision

With a system precision better than ± 20 μm, Struers ViaSampling System ensures the required precision in every step of the coupon preparation process. The stainless steel ViaMount molds keep the sample 100 percent dimensionally stable during curing. The lower part of the mold stays on the sample after curing, locking it into the sample holder, thus ensuring maximum precision.

High Productivity

Drilling and routing are carried out automatically in a single operation, without the need for a tool change. ViaInserter enables accurate positioning of up to six coupons on one set of pins, enabling high-precision preparation of up to 36 coupons at a time. The advanced vision system enabled quick and accurate pinpointing of test coupons with an on-screen magnification of up to 200 times.

Easy to use

Preparation is calibration-free, using factory-calibrated diamond stops. The simple, predefined preparation process ensures well-defined removal through an easy three-step method that may be expanded according to user requirements.
