Process Simplification on Integration of UV Cure Machine with Tape Saw Singulation

Strips that have undergone tape saw singulation will not be completed without the ultraviolet (UV) curing process. To detach the units from the tape, the singulated strips have required further assistance to be loaded for UV cure. Otherwise, hard-to-pick units will be the outcome and sticky residues were usually observed to be attached on the units. Since tape sawn strips requires UV cure, suppliers were asked to engage on upgrading their machine to equip the singulation machine with UV cure. The principle is that after sawing, the singulated strips will be washed and dry normally at the spinner. Then instead of unloading the singulated strips, the machine will pass it first to the inline UV cure machine and then unload when successfully completed the whole process. Through adding the UV curing process in the package singulation sequence, singulated strips unloaded are now ready for the next succeeding process. That way, it would be much help to lessen the handling of sawn strips from one machine to another. The introduction of inline UV cure has simplified the process by automation which increased the security of the units’ quality as well as the productivity of manpower.
