Saving Valuable Time in SMT and Test Programming


Continued from previous page


tation of material supplies, and dif- ferent machine characteristics.


Multiple Vendor/Platform Outputs.


Creating programs and test and inspection information in machine- native format is critical. Much of the information is simple, such as a list of reference designators with an associated x-y position and rotation. The parts shape library must also be provided as it contains information about the camera selections, lighting levels, nozzle selection, and place- ment speed. These settings are sub- jective and often based largely on engineering know-how and experi- ence with material and machine com- binations. The preparation software must


allow rules to be defined in a way that an engineer’s personal experi- ence is useful, and all shape-depend- ent parameters are generated auto- matically. It will also be capable of handling new material data during production if the need arises.


Drastic Reduction in Time Needed


With these areas addressed, the


entire process of preparation is typi- cally reduced from about eight days to half of a day. The time it takes to move a product from one line config- uration to another is also reduced, from two days to a few minutes. Instead of having a one-to-one ratio of products to lines, there is now plenty of opportunity to set up each product on many different lines. The production planning system has the flexibility to use all of its information to sequence work orders according to changing customer demand. These changes in production


planning and engineering can result in up to 30 percent increases in oper- ational productivity. Workers’ skills and experience are more valued as focus is taken from hours of needless duplication and repetitive tasks, and turned towards excellence in engi- neering support.

Multitest: Flexible MEMS Test and Calibration Equipment


Rosenheim, Germany — Multitest, an Xcerra company, has created MEMS test equipment based on a modular design, which combines well-established handling equipment with state-of-the-art test and calibra- tion modules. The company’s portfolio now


includes strip test systems. These systems leverage the capabilities of standard gravity or pick-and-place handling systems for up to eight par- allel test sites. All systems cover the full ambient hot-cold temperature range.


The strip test systems offer the


most for high volumes, though small- er and medium volumes can benefit


from the lower investment require- ments for gravity-based and pick- and-place systems.


Modular test platforms from Multitest.


The handling systems for the


test equipment are combined with a MEMS cart, which houses the


exchangeable MEMS stimulus box. These boxes are designed to customer specific requirements, which keep the system flexible. By exchanging the stimulus box, the cart can be con- verted for different MEMS applica- tions. By undocking the cart from the test handles, the handle is then ready for standard IC testing. This can be used to first calibrate the MEMS part of a device, and then per- form the final electrical test with the same equipment. Contact: Multitest Electronic
