The electronics group of Henkel has introduced a new process, Accelerated Cooling (AC), to be used with its two flip-chip in package non-conductive paste (NCP) underfill encapsulants. The NCP materials, Hysol FP5000 and Hysol FP5001, provide moisture resistance, thermal cycling resistance, expedite the assembly process and are designed for Pb-free interconnects.
Provide an alternative to traditional, mechanical soldering by bonding bumps to the substrate through a Pb-free compatible thermal compression process, eliminating the need for flux application, reflow and cleaning.
AC process heats the device while it is secured by the flip-chip bonder head and then is rapidly cooled during compression onto the NCP-coated substrate. This rapid cooling enables assembly completion prior to any excess heat exposure and, consequently, reduces package warpage, voids caused by moisture and assembly cycle time. Cuts typical cycle time in half (cycle times average 7 sec.).

DataFlex Plus thermal transfer overprinter (TTO) provides on-line printing of variable and real-time data, such as expiration dates, batch/lot codes, ingredients/parts listings, bar codes and logos.
Direct-drive ribbon technology contains few wearable parts, increasing reliability and minimizing downtime and costs associated with ribbon breaks. Standard 1,000 meter ribbon means less frequent changes and higher production line efficiency. Features simple ribbon cassette
Has an intuitive 8.4” SVGA GUI and color touch screen with easy-to-learn, icon-based controls. The standard WYSIWYG job display features a zoom facility to reduce operator error and minimize printing incorrect codes. Has three levels of password protection.
Bi-directional ribbon drive allows unused ribbon to be recaptured following each print. This maintains a 1 mm gap between prints for the complete length of the ribbon, creating more prints per roll.

Axiom X-1022 Dual-Lane dispensing system maximizes throughput during multi-pass underfill operations. Increases the number of units per hour (UPH) produced in high-volume semiconductor applications such as flip chip and CSP underfill. Allows parallel processing on two lanes for continuous dispensing, eliminating lost time in non-dispensing activities. In some applications, a 60 to 80% increase in throughput over single-lane dispensers can be achieved.
Dual-lane capability allows underfill flow-out in one lane while jetting underfill in the opposite lane. Eliminates wait-time by enabling two dispensing processes at the same time.
The conveyors are independently controlled, allowing different-sized parts to be processed in lanes one and two. Programmable flat-belt, dual-lane conveyor allows for a variety of process carriers, including Auer boats, lead frames and custom carriers. Conveyor is SMEMA compliant with a fixed first rail and adjustable second, third and fourth rails.
Configured with up to six stations of contact or impingement heating, three stations per lane: pre-heat, dispense and post-heat. The heat stations ensure consistent substrate heating at specified ramp rates for efficient, reliable fluid dispensing.
Fluidmove for Windows XP software offers advancements in throughput, fluid management and process control. For example, the board or substrate is sensed in the pre-dispense station and the associated dispensing program is automatically loaded.
Mass Flow Control and Calibrated Process Jetting control the critical aspects of the fluid dispensing process in a closed feedback loop.
