Linear Slides
MicroStage 46 linear stage is manufactured from aluminum, the lightness of which reportedly reduces the system's mass dramatically. The slides' patented bearing segment design is said to feature a backlash-free assembly without sacrificing load capacity or smoothness. The linear stage also is available in extended stroke lengths up to 1,840 mm for a range of applications, including multi-axis pick-and-place, insertion, and PCB assembly. Thomson Industries Inc., Port Washington, N.Y.
Epoxy Adhesive
EPO-TEK T6117 single component, thermally conductive epoxy adhesive is designed for high-volume dispensing techniques. Especially designed for use in larger size die-attach and substrate-attach applications, the epoxy reportedly can be cured at 180°C in 15 minutes with very low stress. This produce is said to possess all the physical properties needed to meet today's semiconductor market requirements. Properties are said to include ionic purity, high shear strengths, high radius of curvature, low voiding on cure and low moisture absorption. Epoxy Technology Inc., Billerica, Mass.
Universal Programming System
ProWriter is a flexible programming solution for low- and medium-volume production environments. The universal multi-socket programmer supports gang and set programming for a wide range of device types, with support for programmable logic, memory devices and micro controllers, including Flash-based micro controllers. The system also offers either four or eight fully independent programming sites per unit that can be linked using standard parallel cables to provide up to 48 programming sites, all controlled from one computer. Data I/O Corp., Redmond, Wash.
SMT Interconnect
Solderball Pin is a new SMT interconnect technology that reportedly provides an automation-friendly, high-coplanarity SMT method for interconnecting parallel stacked PCBs. Designed with a high-conductivity copper peg on one end and a solder ball on the other, the pins can be inserted into the daughtercard PCB, which then is placed on the motherboard PCB and reflow soldered using existing processes. A tapered peg design is said to ensure easy insertion and consistent seating on the daughtercard PCB, and the pin automatically compensates for coplanarity variances as solder joints are formed during final reflow to the motherboard PCB. Autosplice Inc., San Diego, Calif.
CLEANING MATERIALS & EQUIPMENT
Underscreen Cleaner
Vortex Plus is an enhanced version of the Vortex underscreen cleaner in which the cassette oscillates as it makes its cleaning pass. The back-and-forth motion is said to produce a scrubbing action against the stencil apertures to achieve more efficient solder paste contaminate removal. The underlying technology of the cleaner reportedly remains unchanged, and the cassettes are identical to the original Vortex design. DEK-USA Inc., Flemington, N.J.
Cleaning Agent
Zestron HC halogen-free, precision cleaning agent reportedly is designed to ensure rapid, residue-free removal of SMT adhesives and uncured epoxies from dispenser needles at ambient temperature. The cleaning agent also is said to be supplied in an aerosol can for manual cleaning. Zestron Corp., Ashburn, Va.
DISPENSING EQUIPMENT
Custom Dispensing Needles
Easy Release custom dispensing needles are for precise, repeatable encapsulation and underfill material application. Each needle is said to be precision-made from a single ..piece of solid stainless steel, as opposed to rolled tubing. The resulting internal surface and ID profile are said to enhance material flow and consistency. The encapsulation needles reportedly feature the standard conically chamfered tip that ensures material transfer from the needle to the substrate or package. Underfill needles also include a "relieved" tip that allows the needle to be adjacent to the chip for better wicking action. Both types of needles are available in 18 to 31 gauges in 0.250 and 0.350" lengths. DL Technology, Haverhill, Mass.
REWORK & REPAIR
Rework Process
High-power, low-temperature hot air rework process is said to save plastic, fiber optic and other thermally sensitive parts from damage. Such component types include glob top BGAs, plastic sockets, CPU sockets, through-hole edge connectors, SMT surface connectors, SMT edge connectors, fiber optic parts, Mylar/flex circuits, RF connectors and RF shields, among others. High-wattage, high-power heat transfer reportedly pumps more thermal energy into the board, but at low, safe temperatures closer to the solder's actual melting temperature. A.P.E. South, Key Largo, Fla.
SMT/BGA Rework Station
B-1 Benchmate Series SMT/BGA rework station reportedly is a flexible system designed for manual alignment and placement or removal of BGA, microBGA, CSP and other surface mount electronic components with repeatable controlled solder reflow profiles. The system is said to feature a unique, rugged gantry-style construction similar to that of a pick-and-place machine. This design also is said to allow the capacity to rework boards up to 14 x 18" in a much smaller footprint with simple board fixturing, stationary bottom-side support, top- and bottom-board clearance, and a forced convection top heater. Precision Manufacturing Tools, Div. of Prodev Inc., Newburyport, Mass.
SCREEN PRINTING
Stencil Printer
XP-508 standalone, semiautomatic stencil printer is designed for maximum flexibility and economy. The print head is a dual-blade DS-II with electric drive, and programmable control of the squeegee speed and pressure reportedly is a standard feature. The printer also is said to feature an LCD display with keypad and function key setup. Manual vision alignment options reportedly are available. Affiliated Manufacturers Inc., North Branch, N.J.
Fine-pitch Printer
SP003 semiautomatic screen/stencil printer reportedly is said to offer perfect printing ..independent of the operator. The printer is said to offer an automatic vertical lift mechanism, allowing parallel separation and leaving behind perfectly printed structures. The solid printing machine also is equipped with a universal screen frame adapter for all sizes and frame types, and offers a magnetic holder for all sizes of single- and double-sided substrates. ESSEMTEC AG, Aesch, Switzerland.
SOFTWARE
Laser Trim Operating Software
TrimSmart laser trim operating software reportedly is for use with the company's TrimSmart and W series of electronics laser trim systems. Running under Windows NT, the software is said to provide simplified programming and ease of use for all trim applications. Through its graphical user interface, ..users reportedly can make quick selections and entries, reducing development time. The operating software also is said to support a full SPC interface, enabling stored or real-time statistical data to be read by a text editor or imported into an SPC program. GSI Lumonics Inc., Wilmington, Mass.
AOI System Software
RTI 4.9 software package reportedly is for the SV-7550 AOI system, and the SVX-2000 automated optical and X-ray system. The software is said to include a host of intelligent features designed to provide PCB assembly manufacturers with increased performance and continued yield improvements. As compared to the company's prior software versions, this software is said to provide the highest defect coverage with the lowest false calls using advanced, intelligent algorithms and an auto-retest option. Photon Dynamics Inc., San Jose, Calif.
TEST EQUIPMENT
Test System
The CmController system is said to incorporate a highly accurate mechanical measurement system powered by a statistical, algorithm-driven software backbone. The basis of the evaluation is to determine machine capability. The system is said to use industry-accepted statistical concepts and methods. The Normal Probability Distribution Curve reportedly is the model the measured data is compared against, and the data spread will indicate its level of quality. Eagle-Eyed One Sales & Service LLC, Hudson, N.H.
Probe Tester
AutoPoint II flying probe tester can be programmed quickly via CAD conversion or teach-in. The system reportedly probes, ..digitizes and learns the signatures of each component or node of a given PCB so that subsequent boards can be tested and diagnosed automatically. The probe tester also is said to be targeted for use in screening and testing low-volume and short-run assemblies. Manncorp, Huntingdon Valley, Pa.
