OLS-1305 | Liquid Encapsulant - Two part Epoxy

Processing Instructions

• Mix component A and B, stir uniformly, and defoam for 5 minutes.
• Prior to chip encapsulation, it is recommended to dry the chip at 150 °C for 2–4 hours and then treat the chip surface using plasma.
• The recommended curing conditions is 150 °C for 4–6 hours. Identify the specific curing settings based on your product requirements.

Precautions

1. Do not preheat Parts A and B as exposure to high temperatures may shorten their usable time.
2. Utilize the mixture promptly after mixing components A and B to avoid excessive viscosity.
3. After dispensing, immediately commence the baking process to avoid moisture absorption, which can slow down the drying process and make the cured product brittle. It is recommended to maintain the relative humidity at approximately 70% when handling the product.
4. Store the curing agent (component B) in sealed jars to prevent moisture absorption and sedimentation.
5. Precipitates may form in the color pastes when they are stored for an extended period of time. As such, prior to use, color pastes must be heated at 60–90 °C until the solid sediments are completely dissolved to ensure uniform color distribution during dispensing.
6. For foam reduction, a defoaming agent may be added, not exceeding 0.3% of the total AB mixture weight.
7. Avoid skin and eye contact. In case of contact, rinse thoroughly with soap (for skin) or clean water (for eyes), and seek medical attention if needed.
8. Maintain a clean and ventilated workplace, using extraction trunks when necessary.
9. Wear appropriate protective equipment and minimize direct contact with the human body. Refer to the Material Safety Data Sheet (SDS) before use.

Using Additives

Optolinq OLS-1305 can be mixed with diffusing agents or color pastes to achieve customer-specific purposes.

Recommended quantity of various diffusing agents and color pastes:

• OPC-R Red Color Paste: 0.1-0.5% by epoxy weight
• OPC-B Blue Color Paste: 0.1-0.5% by epoxy weight
• OPC-G Green Color Paste: 0.1-0.5% by epoxy weight
• ODF-090 Diffusing Agent: 3-5% by weight (LED lamps), 4-8% (LED displays)

Storage and Handling

Store in a ventilated, dry, and clean environment below 25°C. Keep away from fire and heat sources. It is strictly forbidden to store in outdoor environments. At proper storage conditions, Part A has a shelf life of 6 months and Part B a shelf life of 3 months. Shelf life can be extended by using cold storage.
