Abstract: PURPOSE:To prevent any overcompensation from occurring in the case where a feed rate is very slow or the like by integrating each mobile command value after the direction of a mobile command is reversed, and at a time when the integrated value becomes more than the setting value, starting a backlash accelerating compensation. CONSTITUTION:When a code for a mobile command is reversed, integration of value of the subsequent mobile command takes place, and when a position deviation comes to zero or the code is reversed, a backlash counter BC is set to a setting value N, starting to count a backlash period, and when an integrated value of the mobile command, namely, the absolute value of a register R2 becomes more than the setting value XS, a backlash accelerating value A is set to a register R3, and this accelerating value A is added to a velocity command VC calculated by means of position loop handling, through which the velocity loop handling is performed, thus a backlash accelerating compensation is started. Subsequently, this backlash accelerating compensation takes place till the backlash counter BC comes to less than zero.

Title: Method for inspecting electronic part
Inventor: SHIMOKOSHI MASAYOSHI
IPC: H01L21/66
Filed: 1995-05-09
Abstract: PURPOSE: To inspect without causing an electric shortcircuit of probe pins, by bringing a probe pin in touch with a body to be inspected, impressing an amount of overdrive and horizontally moving a probe card in a specific range. CONSTITUTION: A probe card is brought in touch with a measuring terminal 5 of a wafer 4 to be inspected thereby adding an amount of overdrive. In consequence, vertical probe pins 1 are bent and deformed in random directions. If the probe card is moved in a horizontal direction at this time, the pins 1 are bent in one direction and prevented from being in touch with each other. In this case, when a moving amount dμm of the probe card in the horizontal direction to a length Lμm of the pin 1, namely, d/L is less than 0.01, the bending direction of the pins 1 may not be controlled in some cases. If d/L exceeds 0.30, front ends of the pins 1 may shift from on the terminals 5 of the wafer 4. Therefore, the moving amount and the length of the pin 1 are set so that d/L satisfies 0.01-0.30.
