Roswell, GA — Today’s electronics are used in a range of industries and ex- posed to widely varying temperatures. Safety-related electronics, such as those in medical technology, automotive and aerospace, must function reliably at all tem- peratures. Rehm is now offering its Securo systems to heat or cool assemblies and pre- pare them for hot or cold functional tests. Rehm’s Securo Plus system is designed


for hot functional tests and the Securo Minus for cold. The systems operate in normal air or nitrogen atmospheres. To test the winter performance of sensi-


tive electronics, functional modules are first cooled to temperatures of –49°F (–45°C). How- ever, to simulate the installation environment of a vehicle, modules are heated to be- tween 176 and 248°F (80 and 120°C). The Securo systems are compat-


ible with other measuring equip- ment. This allows extensive function- al monitoring and secure quality con- trol. Analysis and documentation tools provide a transparent process. Safe testing and measuring


methods are increasingly relevant and have already become standard in ana- lyzing the resistance of electronic com- ponents. In the aerospace industry, for


DuPont Expands Pyralux and Riston Families


Wilmington, DE — DuPont Intercon- nect Solutions has introduced several new products across its DuPont™ Pyralux® and Riston® product families to address a diverse set of needs for both the manufacture and perform- ance of advanced electronics devices. Pyralux AG is an all polyimide,


double-sided copper-clad laminate that is offered in both sheets and rolls with global availability and is suitable for use in consumer, medical and auto- motive applications. Pyralux GPL is an adhesive that is specifically formu- lated for high-speed, high-frequency flexible circuit applications. It exhibits excellent thermal resistance, peel strength and UV laser drilling process capability. Riston DI3000 is a multi-wave-


length, dry-film photoresist for pat- tern plating on multilayer boards. High adhesion and chemical resist- ance delivers yield by eliminating lifting and breakdown defects in cop- per, tin or gold. Riston DI5100 is designed to be


an optimum solution for the mSAP process. Made for smooth copper high adhesion on isolated resist line, this film delivers high-density cir- cuits. Riston DI9200 is a high-densi- ty interconnect film for print and etch processes. High resolution and adhesion, combined with excellent lamination conformation ensures high yields. Fast photospeed at mul- tiple LDI wavelengths ensures high


productivity. Contact: DuPont, 200 Powder

example, the sun-facing side of a spacecraft can become extremely hot, as in the vacuum of space there is no air for cooling. However, since the temperature in space is –454°F (–270°C), the spacecraft is simul- taneously exposed to extreme cold. Despite this extreme temperature, the technology must be completely reliable. For such fields of application Rehm offers


systems that can accurately simulate these ex- treme environmental conditions by selectively


heating and/or cooling the assembly. Contact: Rehm Thermal Systems, LLC,
