room can collect particles that may spread and interfere with deposition of circuitry. Vacuum hoses can be stepped on or tripped over. In addi- tion, a vacuum hose attached to a wafer wand restricts dexterity dur- ing the handling operation, which may result in dropped, chipped or scratched wafers. A portable battery- powered wafer wand such as the PORTA-WAND eliminates all of these issues. The handle of this tool contains a miniature vacuum pump, a battery as the power source and a press fit connector on the front of the tool that will accept a variety of dif- ferent handling tips. The button on the front of the tool is depressed to engage the vacuum. The tip is placed flat against the substrate to be han- dled and it is firmly gripped for han- dling. Releasing the button turns the

ect, or might initiate a live technical support chat from their office in a time zone 14 hours apart. Electronics design and manufacturing is a global business, not a regional one; serving the industry is now a round-the-clock enterprise. In fact, Sunstone recently added
24/7/365 live chat via the Sun -
stone.com website. Now customers can ask questions or interact with a Sunstone Technical Support expert through the phone, through asyn- chronous written form (email) and through synchronous written form (chat). Whether the value of live chat comes from time zone differences, language preference, physical chal- lenges, or other issues, Sunstone makes their experts as accessible as possible, thereby increasing their value as a consultant on every cus- tomer’s prototype work.
Production Yield As mentioned, production yield
levels are a key leading indicator for ongoing service levels during the prod- uct’s lifecycle. Though yield becomes critically important for production, it is still of importance through the pro- totyping process. Sunstone’s build processes, coupled with the consulta- tive expertise and accessible experts, means that Sunstone delivers a higher level of prototype yield overall. And since this higher yield reduces waste and production costs, Sunstone is able to maintain a competitive pricing structure against lesser-performing competitors. PCB manufacturing efficiencies
can have a number of direct impacts on a design team’s effectiveness. When the design team uses a proto- type manufacturing partner that places a deep-rooted cultural value on working together with customers to ensure accurate, efficient, speedy fulfillment of orders for prototype boards, then everyone benefits.

tool off and the substrate is released. All of the applications for vacu-
um handling are too numerous to cover in this limited space. Most applications can be solved using off- the-shelf pick-up tips. Some applica- tions require custom tips. Vacuum tweezers provide industry with solu- tions for manual handling of delicate parts without damage, dropping or contamination. Contact: Virtual Industries, Inc.,
