MRSI-175UF Capillary Underfill Dispenser Introduced for the Flip Chip Market

North Billerica, Mass., USA – MRSI, a Newport Corporation Company, announces the addition of a new underfill system to its 175 product line of dispense systems with the introduction of the MRSI-175UF. This system is targeted specifically to the flip chip underfill dispense market. Depending on customer need, the MRSI-175UF can be configured to meet application-specific solutions, e.g., single or dual conveyors, single or dual dispense head, rotary or linear positive displacement pump. This flexibility allows the system to be used in development or in production.

The Linear Positive Displacement Pump design offers very tight process control, high dispense accuracy and consistent repeatability needed for high volume production. With closed loop encoder feedback, the pump is capable of holding very precise process control tolerance over extended periods of time, substantially reducing frequency of calibrations compared to competitive pumps. The pump was designed to keep routine maintenance quick and easy by using standard inexpensive disposable components.

In addition to the pump technology, the MRSI-175UF offers parallel processing conveyors that reduce time associated with preheat, load, unload, transfer, and underfill material flow. As substrates are being pre-heated on one conveyor, material is being dispensed on the other. As a result, MRSI-175UF offers higher throughput, higher performance and higher productivity at the lowest cost of ownership.

MRSI, a Newport Corporation Company, is a leading supplier of dispense and assembly systems for the semiconductor, photonics, and microelectronics industries.

Newport Corporation is a global leader in the design and manufacture of high-precision components, instruments and integrated systems for the semiconductor front-end equipment and aerospace/research markets and back end packaging systems for the communications market.
