RUBBER EPOXY STAMPING TOOLS (REST)
RUBBER EPOXY STAMPING TOOLS (REST)
Epoxy stamping was used extensively before the appearance of more sophisticated dispensing techniques. Today, stamping tools still represent a viable and inexpensive solution for prototyping, small production series or for very small die size assembly.The adhesive paste is place in a rotating cup which surface is levelled by a blade set at the required height. The stamping tool is plunged into the paste and then transfers the collected amount of paste on the target pad.
TIP CONFIGURATION REST Rubber Epoxy Stamping Tool, from die size .051" / 1.30mm and above. SEST Steel Epoxy Stamping Tool, from die size .006" / 0.15mm and above.
REST : RUBBER EPOXY STAMPING TOOL The design provides a dot matrix epoxy print out. The layout of the tool pins assures a consistent amount of die attach material to be placed on the pad area.
Three rubber pad patterns are available with different dot diameter and pitch. 1) Pad # 3, dot diameter .0118" / 0.30mm , pitch .031" / 0.80mm 2) Pad # 5, dot diameter .0197" / 0.50mm , pitch .040" / 1.00mm 3) Pad # 6, dot diameter .0236" / 0.60mm , pitch .040" / 1.00mm How To Order Shank Style - Tip - Pad # - Dot Pattern & Length Config. EXAMPLE: 2102 - .625 - REST - 5 - 4 x 4 EXAMPLE: 2102 - 16 - REST - 6 - 8 x 4 x 3

HOW TO SELECT THE RIGHT RUBBER EPOXY STAMPING TOOL
Even if empirical experiments give the only true image of the final dispense output, we can approach the desired result by considering the following rule of the thumb. The epoxy coverage of the tool chosen must be larger than the die size while the physical Pad pattern PL x PW should be equal or smaller than the die size. For the standard pad layouts, the value PL ,PW, DL and DW are given in the table and can be calculated with the following formula:
When the die is pressed onto the epoxy layout, enclosed by the dot outline DL x DW , the die attach material will spread out and the epoxy coverage will be extended by approximately : + .008"-.012" / 0.20-0.30mm for Pad # 3 + .020”-.024” / 0.50-0.60mm for Pad # 5 + .024” / 0.60mm for Pad # 6 Whenever possible it is advisable to choose a pattern that has closer gap between the dots. For thick layer deposition, it may be necessary to print the same substrate twice.
