AIM will highlight its lead-free soldering materials, including the SN100C lead-free alloy, in booth 5434 at AT Expo in Rosemont, IL. In addition, a live lead-free selective soldering demonstration with the alloy is in booth 5437.
SN100C, created by Nihon Superior in Japan, is comprised of tin, copper and a small amount of nickel.
The small amount of nickel modifies its behavior so that in wave soldering it exhibits fluidity comparable with tin-lead solder. Excess solder drains easily off the joint, so bridges and icicles are avoided. Provides smooth, bright, well-formed fillets which make inspection easy.
Does not contain silver or phosphorus, is less aggressive towards the copper of tracks and pads or the stainless steel components of soldering equipment. Has a low dross rate.
Polyonics introduces 1 and 2 mil color polyimide labels. The labels are
coated with a permanent pressure-sensitive acrylic adhesive and a high
opacity, medium gloss topcoat available in six tinted colors ¾ pink,
yellow, orange, blue, green and violet. They are thermal transfer
printable and scan with both visible and IR scanners. Barcode labels
made from the materials reportedly demonstrate excellent performance in
lead-free wave solder environments, which range from 260º to 290ºC.
Designed
for barcode or alphanumeric identification of PCBs or electronic
components, can withstand mixed circuit board processes, on either the
top or bottom side of the board. Said to have excellent resistance to
harsh fluxes, cleaning agents, saponifiers and wave solder
environments, and resist common methods of cleaning.
Polyonics
developed the labels, which will survive both standard and lead-free
processes on top or bottom side of the board, for manufacturers looking
to color code production/process lines. Some companies
choose to use the plain white polyimide labels for standard
“non-compliant” subassemblies, and a color-coded label (e.g., pink,
yellow, orange, blue, green or violet) for the compliant
products.
Rochester, NY and Bromont (Quebec), Canada -- Hover-Davis will offer Cogiscan RFID hardware and software applications compatible with its range of component feeders, including tape feeders, label feeders, and Direct Die feeders.
By combining the Cogiscan Smart Material Control technology with its component feeders, Hover-Davis will be able to provide a one-stop shop for Intelligent Feeding Solutions. Features of intelligent feeders include: Identify and track components and feeders with barcode and RFID Provide real-time visibility of all materials on the shop floor Reduce waste of time and materials Eliminate human errors and improve productivity Generate complete component traceability reports Standardize data acquisition across multi-vendor lines Enable communication between feeders, machines and systems
CAT 35 ILDS (Integrated Liquid Delivery System) dual-mode spray head is an alternative to conventional air-atomizing, film coating and dispensing technologies.
Consists of an ultrasonic transducer with a titanium spray forming head and integrated liquid and air applicators. Has two modes: narrow (5 mm pattern width) and wide (3 to 25 mm pattern width). Applies a thin, defect-free coating 0.5 to 5 mils in thickness, said to provide excellent uniformity.
Nozzle-free spray head works with urethanes, acrylics, water-based, solvent-based and 100% solids UV curable conformal coatings and is compatible with all Prism Systems.
New software for In-Sight vision sensors reportedly improves workflow, eases integration and speeds deployment of vision sensors on the factory floor:
In-Sight Explorer 3.1 features a Windows XP look and feel, and supports the use of industry-standard OPC communication tags. In-Sight OPC Server makes it easy to exchange data with other OPC programs and systems including PLCs, distributed control systems (DCS) and distributed I/O networks. In-Sight ActiveX Display Control allows users to integrate In-Sight images and display graphics into third-party HMI and SCADA packages.
Christopher Associates will introduce two automatic optical inspection systems, as well as a laser robotic soldering system, at booth 6102 during Assembly Technology Expo in Rosemont, IL. This will be the North American introduction of all three products.
NSpec DL 18 is the latest addition to the Marantz (Tokyo, Japan) AOI product line. Offers high speed first article inspection, advanced illumination and very high resolution optics, can even inspect 01005 components at very high speeds.
KY 3020T bench top, 3-D solder paste inspection system from Koh Young Technology (Seoul, Korea) offers the accuracy and speed of the standard inline systems for high mix/low volume applications.
Model 414L laser robotic soldering system from Japan Unix Co. Ltd. was developed for lead-free processing with reduced cost of ownership.
