Abstract:
An apparatus (5) for dicing an integrated circuit substrate having a loader (30) for loading the substrate to the apparatus, said substrate loaded in a first direction corresponding to a loading axis, an inlet rail (35) said inlet rail including a first block (75) movable along said inlet rail (35) to which is loaded the substrate from said loader, wherein said inlet rail is arranged to deliver the first block (75) and substrate towards a chuck table (60) in a second direction orthogonal to the loading axis.
Abstract:
The invention discloses a unit lifter assembly for lifting singulated integrated circuits singulated from a semiconductor substrate including a plurality of rows of unit lifters and a plurality of actuating means, each operatively engaged to at least one unit lifter, wherein each actuating means is arranged staggered one after another so that a pitch from one actuating means to another is minimised.
Abstract:
A system for singulating an IC unit from a substrate, said IC unit having a combination of linear and non-linear peripheral edges, said system comprising a profile cutting device for cutting the non-linear portions of the IC unit; a longitudinal cutting device for cutting the linear portions of the IC unit, said cutting means located within a singulation zone.
Abstract:
A punching system for singulating IC units comprising: a punching assembly arranged to receive a substrate and singulate said substrate into the IC units; a rotary carrier rotatable from a first position to a second position said rotary carrier arranged to receive said units at the first position and carry said units to the second position through rotation; wherein said rotary carrier includes recesses for receiving at least a portion of the units. A punching assembly comprising a die block having recesses for receiving selectively replaceable inserts wherein said inserts correspond to a punch pattern specific to a predetermined IC package arrangement.
Abstract:
The present invention relates to a net block assembly in a system for positioning singulated integrated circuits, having a net block surface partially covered by a two dimensional array of first and second elements, each first element having an aperture provided with vacuum adapted to receive an integrated circuit and each second element projecting from the surface said net block assembly including a plurality of rows of first and second element arranged in a chequer pattern, wherein the number of elements in the row is an odd number and a buffer row in the array having two first elements arranged adjacent to each other, wherein the number of elements in the buffer row is an odd number.

Abstract:
A method for inspecting and sorting a plurality of IC units comprising the steps of: delivering a frame containing said IC units to a unit picking station; conducting a first inspection of said units during the delivering step and recording the subsequent result; removing said units from the frame, and moving said units from the unit picking station to a flipping station; conducting a second inspection of said units during the moving step and recording the subsequent result; flipping said units to expose an opposed face said units; conducting a third inspection of said opposed face and recording the subsequent result, then; sorting said units into categories based on the recorded results from the first, second and third inspecting steps.
