Glossary

We frequently update our glossary with terms that may be used in our products and in our industry in general.

 

  • Abel

    Advanced Boolean Expression Language.  An early hardware description language developed for PLD-based designs.

  • Accelerator

    A specialized piece of hardware that speeds up a software-based task. Usually used for speeding up simulation.

  • Alignment Offset

    Location on the body of a device where the last alignment measurements are taken by the Cyberoptic sensor. A digital caliper can be used to take physical measurements of the device in order to calculate the "theoretical" alignment offset. For components with leads, the alignment offset needs to see the "bending of the leads". Keep in mind that the bellows in the pick rod compresses once the device is picked up, which changes the "theoretical" alignment offset. Trial and error in increments of 5 mils in both directions from the "theoretical" value should be tried to optimize this value. Use the log file to read the actual widths that the Cyber Align camera "sees" in order to determine at what height the device is being scanned. The alignment offset can then be adjusted based on this reading.

  • Alignment Tolerance

    The alignment tolerance are the allowed length and width measurements allowed before a device is rejected. The alignment tolerance should be kept below 20% as a general rule. Increasing this tolerance to make a device pass alignment is a sign that some parameters, including device narrowest length and device longest length are not entered correctly. The more accurate the narrowest and longest length measurements are, the lower the alignment tolerance can be in order to detect damaged devices more effectively.

  • Allow Operator To Retry Mispicks

    A global programmer setting, found via the Autohandler > Pick-and-Place > Settings menu.

    When this option is checked, then the Retry notification window is displayed to the operator when a pick failure occurs on a Tray, Shuttle, TS1500, Laser and Programming Site.

    NOTE: If this option is Enabled AND when Trays, Shuttles or TS1500 are set to be both the Source and Destination, they will not be automatically unloaded until ALL pick errors have been cleared by the operator.
    This setting is therefore not suitable when the system is intended to be run unattended until completion.

  • Analogue

    A continuously varying signal. For example, if an analog signals range is from 0 to 5 volts, the signal can assume any voltage within that range such as 1.2, 2.4 or 4.7 volts. Microprocessors and microcontrollers usually cannot process analog signals directly and require conversion by an A/D converter before they can process the signal.

  • Analogue Simulation

    Modeling or simulation of an electronic circuit using representations of the actual circuit voltages, currents, and component values instead of simplified digital state representations.

  • ASIC Emulation

    Also Logic Emulation. The use of programmable circuits usually based on FPGAs, to emulate the design of an ASIC or an IC before it is built. ASIC emulation allows designers to check the operation of a design before committing the time and money required to fabricate the IC. Emulation serves the same purpose as simulation design verification but is much faster because it is based on hardware rather than software.

  • BPWin

    BPWin is the software used to control manual and automated programming systems from BPM Microsystems.

    All BPM programmers must be connected to a Windows PC running this software to be able to communicate so that devices can be programmed.
    New versions are regulary released which contain new features, updated algo database and/or any platform fixes.
    The software is free to download, but concurrent and automated systems require an active software support contract to enable full functionality.

  • Diagnostics

    A function in BPWin to test the operational condition of a connected programmer and/or socket module.

  • Empty Socket Test

    A global programmer setting, found via the Autohandler > Programmer > Settings menu.

    Allows for an empty socket test to be performed on each socket, to ensure that parts have been successfully removed and to prevent any chance of "Double Stacking" parts.

    Empty Socket Test is completed automatically every time the interlocks are opened or when a pick failure occur.
    Using this feature, allows you to specify an Interval of when additional Empty Socket Tests will be completed during a job.

    Enter a value of 0 to 65535, where 0 disables the addition EST function, so EST is only performed when interlocks are detected open or when a pick failure occurs.  If a value of 5 is entered, then EST will be performed after every 5th device has passed through a site.

  • Maximum Number Of Site Failures

    A global programmer setting, found via the Autohandler > Programmer > Settings menu.

    Allows for programming sites to be automatically disabled, if the maximum number of site failures value that has been entered has been reached.

    This is useful if instances where a worn socket is causing repeated continuity failures on a site, which in turn affects the systems throughput (DPH).  By disabling the bad site, the system can operate for effeciently by not wasting time placing and picking parts from that site.

    Enter a value of 0 to 65535, where 0 disables the function.

  • Operation failure retry attempts

    A global programmer setting, found via the Autohandler > Programmer > Settings menu.

    This is the number of times a device will be picked and re-placed in the same socket and the operation retried when the Retry on Continuity or Retry on ID Check failure selections boxes have been selected.
    The Retry on Continuity or Retry on ID Check failure selection boxes are found directly underneath the Operation Failure Retry Attempts field.

    Enter a value of 1 to 20.
    To disable the function, then uncheck Retry on Continuity or Retry on ID Check failure boxes

  • PSU Test

    A test function that allows read back of the internally measure PSU values to ensure that the programmer is running at the correct conditions.

  • System Of Units

    A global programmer setting, found via the Autohandler > System > Settings menu.

    A system parameter to change the way that physical quantities in BPWIn are displayed.

    Default value is U.S. customary which displays values as "mils", with option to change to SI Units, to display values in mm or um.

    Some values recorded in the Black Box files will still be shown in U.S. Customary regardless of this setting.
