Advanced Resistor Trimming System
Large format for full-size PCB panels.
The standard RapiTrim Trim and Test system accepts substrates up to full size PCB panels. The system uses four independent flying probes, eliminating restrictions on component location, size, orientation and layout. Circuits can be as large as the substrate itself and probing of dense designs is effortless - this previously required multiple passes with multiple probe cards. Time and cost to trim a PCB is dramatically reduced. The ease of job creation combined with fixtureless probing allow the RapiTrim systems to outperform older technology in both high volume production as well as low-volume, high-mix situations.
System Features Include:
Optional Features and Hardware
Cart loading automation allows for carts and trays of panels to be loaded into the system (side pods shown above and detail left). Panels are loaded by vacuum pickup.
Compact tray autoloader within the core system footprint (shown below).
Automatic pickup and vacuum zones for multiple panel formats.
Slipsheet pass-through handling for both autoloader styles.
Configurable for large panel and continuous web processing
Compatible with roll-to-roll web handlers
The SM200 base signal routing switch card provides expanded signal routing functionality for active trim and specialized measurement applications.
External Instrument Support
The trim controller can interface to external instrumentation for passive and active trim operations using standard LAN (LXI) interface. Such instrumentation can be digital multimeters, source-measure units, signal generators, power supplies or external loads.
Custom part fixturing for hybrid circuits or other small substrates
These are designed in collaboration with the customer and supplied with the system. Example of a custom 9-up fixture with locating pockets and vacuum hold-down.
Automated probe tip changing
Anytime a change in probe tips is required, the current set (one or all) can be unloaded into an empty holder and fresh tips loaded from an adjacent holder. Probes are automatically calibrated and trimming can resume, all without operator handling.
Barcode or 2-D matrix code reading
Used for panel identification, and can be manual or automated.
Process sequence customization
The trim process operation can be customized using a sequence of defined sub-tasks. This allows the processing of DUT components to be tailored to the specific application. Supported sub-task operations include conditional processing, looping, control of voltage and current sources and measurement instruments (both internal and external), among others.
