Product Description

RCS 400 Rubber cleaning sheets are carcinogen free materials that are safe to handle and use compared to other rubber cleaning versions. They are used to eliminate pollutants and stains formed on the mold surface and perform well in a wide range of molds. They require a mold temperature of 165 - 200°C and have a curing time of about 300-600 seconds depending on your cleaning conditions. These sheets perform almost similar to other versions while having the advantage of being safe and easy to use, something that assists in reducing processing time.

RCS 400 sheets have good flow characteristics which enable them to clean mold corners and thin gate areas easily. Unlike melamine compound cleaners, RCS cleaning sheets can clean the air ventilation areas without causing mold abrasion or corrosion. At the same time there's no need for dummy lead frame or preheating and they need 3-5 shots to be effective, something that reduces cleaning time and leads to improved production time and productivity. For a safe and clean process we advise a combination of RCS 400 with WS300 wax conditioning sheets.

RCS 400 Rubber cleaning sheets are suited for IC, Semiconductors and Discrete molding processes  and have relatively low to medium viscosity. Are you molding LED and need higher viscosity? Contact us for the products that we have under development.

Technical Specifications

General Properties
The color
Compression Pressure 80 - 130 Kg/cm2
Specific Gravity
Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.

For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

Curing Conditions
Curing Schedule
Curing Schedule
Curing schedule is the time and temperature required for a mixed material to fully cure. While this applies to materials that cure with heat, there are also other materials that can be cured with UV.

Even though some materials can cure on ambient temperatures, others will require elevated temperature conditions to properly cure.

There are various curing schedules depending on the material type and application. For heat curing, the most common ones are Snap cure, Low temperature cure, Step cure and Staged cure.

Recommended cure type, schedule, time and temperature can always be found on the Technical data sheets.
Cure Time 5 - 7 min
Mold Temperature 170 - 185 °C

Additional Information

A normal cleaning Cycle for BGA is:

2 shots of RCS400 BGA Dissolve and 2 shots of RCS400 BGA Clean

A normal cleaning and conditioning Cycle for Diodes is:

5 shots of the RCS400 - Diodes cleaning + 2 shots of the WS300 - Diodes conditioning sheets
