Purpose:

HALT, HASS, POS, and ESS stress systems process currently being employed to accelerate the discovery of design weaknesses and to find manufacturing defects in products before a product is manufactured and introduced.  This can result in reduced product costs, improved product reliability, accelerated time to market, and reduced warranty costs.

Quanta's Patented ESS System:

If proper environmental stress screening equipment is used, this is a very effective and economic tool to be applied to the design verification of a new product or to find problem(s) in an existing product. Unfortunately, ESS equipment currently available in the market utilize pneumatic hammers to generate the vibration input to the product. There are several inherent technical drawbacks to pneumatic hammer designs:

Product Line Screening System

Quantas newest invention is a Production Line ESS system. It employs a pair of accordion support structures, for multiple PCBs, that take turns moving onto a shaker head expander and into a fast ramping chamber. The system ramps quickly between high and low temperatures and vibrates at the temperature extremes to produce a highly accelerated stress screening on the product, and total test time per run is about 10 minutes. This cutting edge technology is a must for wringing out infant mortality on your product more efficiently than current methods allow. Contact Quanta Laboratories for a detailed description of this patented system that will reduce the time and cost for screening your products.
