TIPS FOR THIN & FRAGILE DIE
RTR-D2 & RTR-D3
For some applications, like handling large thin die, the preferred vacuum
cavity is different than the traditional round or rectangular shape found on
common rubber tips. The desired design is rather a cross groove or X sign or
a multi hole configuration. This feature prevents the die to warp inside the
vacuum cavity and to cause poor wetting or incomplete epoxy coverage during
die placement. The outer shape of the tip depends on the size of TL/TW:2 or 4
tapered walls or vertical walls. Various custom vacuum channel or cavity
configurations are possible on request.
RTR-D2-CCG:RECTANGULAR TIP RUBBER WITH DOUBLE Y CROSS-GROOVE
RTR-D3-CCG:RECTANGULAR TIP RUBBER WITH CROSS-GROOVE
RTR-D3-MH:RECTANGULAR TIP RUBBER WITH MULTI-HOLE
The Maximum TL or TW dimension for RTR-D2-CG, RTR-D3-CG and RTR-D3-MH s
.472" / 12 mm. By
