Nortech: How ezLOAD Board Support Boosts Revenues
Continued from page 69
voids and solder bridging and has achieved great results each time.
Reduced Changeover Time The ezLOAD PCB support sys-
tem from Count On Tools not only reduces changeover times, but improves product build quality, increases revenues by providing sig- nificant cost savings, and can elimi- nate component damage during the assembly process. The product incorporates a
modular universal design with only two parts: the support pad and the base. There are no mechanical func- tions to fail and it requires no air, electronics or communication from the user. The support pads utilize ESD-safe active grip technology to securely hold boards during the assembly process. The support pads are capable of supporting densely populated, double-sided boards. The ezLOAD support pads are extremely durable because of the soft, flexible design, and are proven to be reliable after testing in the most hazardous conditions. In addition, the ezLOAD base is precision-machined from air- craft grade aluminum alloys to pro- vide a strong and reliable support for boards. The magnetic locking base enables a quick, easy installation in the user’s machine. Other base designs are available for machines that have non-magnetic tables.
Most importantly, the ezLOAD
PCB Support System is affordable compared to competitive products on the market. Each component can be replaced or upgraded based on the customer’s specific product, equip- ment or application. The ezLOAD PCB Support
System is simple to use: just place the unit on the equipment’s board support table and align as required. Multiple units can be arranged in rows (X and Y) for more support on larger boards. The ezLOAD PCB Support
System is compatible with any SMT equipment, from pick-and-place to chipshooters, screen printers, dis- pensers, AOI and others. It can be customized depending on machine requirements, specialized compo- nents or specific design application requirements. “With the ezLOAD system, we
continue to notice a significant reduction in defects on component issues including micro BGAs, fine- pitch ICs and leadless components,” added Fritz. Contact: Nortech Systems, 1120

vide a maximum field of view of 24mm and magnification ranging from 1X to 1,000,000X. While stan- dard VEGA series SEM systems are supplied with conventional tungsten- heated-cathode electron guns that can be used in either high- or low- vacuum modes, the firm also offers an option for a lanthanum hexa-
boride (LaB6) electron source which is claimed to provide much improved viewing resolution and brightness compared to the conventional elec- tron sources.
Shrinking Size Although such room-filling sys-
tems offer a great deal of analysis power, in applications as wide rang- ing as biological research to military semiconductor electronics, a recent trend in SEM systems has been to pack more power into smaller pack- ages. Many of the firms supplying large-scale SEM systems are now also developing more compact sys- tems that are more easily incorporat- ed into research and production facil- ities. For example, the TM3000 Tabletop Microscope from Hitachi High Technologies America is a com- pact SEM physically not much larger than an optical microscope. Well suited for semiconductor research, it handles samples as large as 70mm in diameter and 50mm in high, provid- ing stage motion of 35mm in the x and y directions. It provides magnifi- cation from 15X to 30,000X, with dig- ital zoom to 120,000X. Another compact system from a
leading SEM supplier, model 8500 from Agilent Technologies (
www.agi-
lent.com), is a field-emission (FE)
SEM that is not much larger than one of the company’s desktop laser printers. It offers several imaging techniques to allow users to study thin-film materials and a variety of substrates, including glass. The SEM system operates with continuously variable imaging voltages from 500 to 2000V for flexibility with a wide range of target materials, and pro- vides better than 10nm resolution at 1000V. It handles samples as large as 100 x 60mm with a viewable area as large as 50 x 30mm. Among the growing number of
suppliers of desktop SEMs, Phenom World (
www.phenom-world.com) is fast finding interest in its compact personal-computer (PC) controlled SEM systems for applications not formerly served by SEM technology. The company’s Phenom product is a desktop SEM which is designed to be as easy to use as an optical micro- scope, but providing the high magni- fication of an SEM. With magnifica- tion capabilities to 100,000X, the compact SEM system has found favor among law-enforcement users, for forensic analysis and crime-scene investigations. As SEM technology expands
and is made more accessible, in smaller physical systems that are easily operated under PC control, the number of applications for SEM tech- nology in electronics and other fields will continue to grow. With the capa- bility of many SEM systems to store captured images as digital files, these SEM systems will also play increasingly important roles in the computer modeling of electronic devices and circuits. r
