How Rubber Cleaning Sheets Clean Epoxy Molding Compound Mold?

The Caplinq’s RCS Rub­ber Clean­ing Sheets is a mold die clean­ing mate­r­i­al that was devel­oped for clean­ing the mold stains-organ­ic residues, epoxy resins. These are the residues that are left in the deep cav­i­ties dur­ing the process of semi­con­duc­tor device encapsulation.

RCS Series Rub­ber Clean­ing Sheets have a mold die release agent, which enhances the releas­ing abil­i­ty of the mold die sur­face. They are main­ly used for the removal of con­t­a­m­i­na­tion of the molds, which are used in the phys­i­cal and chem­i­cal mech­a­nism of the semi­con­duc­tor cir­cuits includ­ing diodes, ICS’s, tran­sis­tors, and LED’s.

And, RCS series sheers are best suit­ed for clean­ing of pro­duc­tion lines that work with Elec­tro­mag­net­ic Com­pat­i­bil­i­ty. The LINQSHEET clean­ing sheets series con­sist of RCS 100, RCS 200, RCS 300, and RCS 400. These sheets fea­ture a good flow char­ac­ter­is­tic that allows them to clean small, thin, and ven­ti­la­tion areas.

The RCS100 Rub­ber Clean­ing Sheets by Caplinq works with a wide range of molds. They can with­stand a torque of 6lb-in to 53 lb-in and cures the sur­face just in 53 sec­onds. The RCS 200 has the low­est odor and the strongest results. The RCS 300 is an amine-free clean­ing alter­na­tive, and RCS 400 Rub­ber Clean­ing Sheet pro­vides a car­cino­gen free clean­ing alternate.

Of the whole RCS series, RCS 100 has the highest cleaning performance.


1. Use the stan­dard mold­ing con­di­tions- The cur­ing pro­ce­dure takes place under high pres­sure, and high tem­per­a­ture as the Rub­ber Clean­ing Sheets gen­er­ate the active components.
2. Set the con­di­tions accord­ing to the mold cav­i­ty depths and place the clean­ing sheets over the cav­i­ty. Seal the mold and let the cur­ing pro­ce­dure stay for five minutes.
3. Open the press; remove the cured sheets and check the cav­i­ties for the stains.
4. Repeat the above steps till the mold cav­i­ty is com­plete­ly clean and until all the stains are trans­ferred to the cured mold­ing compound.
5. At last, remove the resid­ual rub­ber with a shot of compression
For best clean­ing expe­ri­ence, keep the gap of 0.5 mm~1.5 mm between the molds.
When­ev­er you are using LINQSHEET Rub­ber Clean­ing Sheets, you will expe­ri­ence no cor­ro­sion or abra­sion. No pre­heat­ing or dum­my flame is required for increas­ing the pace of the pro­ce­dure. They fea­ture a stan­dard size that will fit a wide range of molds lead­ing to increas­ing the pro­duc­tiv­i­ty and an improved time frame results.
