Ultrasonic Systems will demonstrate the Optima Fluxing System at Productronica next month, in Hall A4 Booth 158. A new Ultra-Spray head produces a more vertical spray pattern, ensuring through-hole penetration when using water-based VOC-free fluxes.
Ultrasonically atomizes VOC-free flux into a fine mist, and then traverses the spray under the circuit at programmable speeds, ensuring flux penetration of the plated-through holes.
Can process circuit boards up to 24” (61 cm) wide and 0.250” (6.35 mm) thick, with plated through holes of 0.015” (0.381 mm) in diameter.
Micro-Line Digital Dispensing Head consists of a high-speed liquid metering valve and a precision nozzle.
Applies conformal coatings in precise lines or dots down to 1 mm with the liquid flow rate set electronically with the Prism software. The coating is applied at a distance from 5 to 15 mm between the nozzle tip and the substrate. The technology is said to be more effective than conventional needle dispensing.
GETEK HR high speed, low loss laminates and prepregs are CAF resistant, lead-free assembly compatible materials said to deliver enhanced thermal performance and high reliability, while enabling PWB fabricators to experience substantially improved FR-4 processability.
Has low dielectric constant, low loss and low z-axis expansion.
“GETEK HR, with its low z-axis expansion and high decomposition temperature, is well suited for thick multilayer PWBs requiring improved electrical performance, as well as high speed and low loss products that will be assembled in a lead-free process compliant with the EU’s RoHS directive.” said Ed Kelley, director of OEM marketing.
With manufacturing in both the U.S. and Taiwan, is readily available in prototype to high-volume quantities. Customers UL approval for manufacturing with GETEK will also be able to use GETEKHR.
Used for a broad range of applications that include telecommunications equipment, high speed computing and storage, test and measurement equipment, medical electronics, IC substrates, and RF and wireless electronics.
