Description

Technical Field

[0001] The invention belongs to the technical field of extraction equipment, and in particular relates to an epoxy molding plastic ion-sealed extraction device. Background Art

[0002] Epoxy molding compound is a thermosetting product. If there are too many free ions in the epoxy molding compound when the package is in the presence of moisture, it will corrode the bonding wires in the packaged chip, further affecting the reliability of the package. Therefore, the ion content of the product needs to be tested during product research and development and mass production. At present, the extraction method is used to detect the ion content of the product. The material is first subjected to 20 hours of pre-extraction treatment, and the extract is taken for ion testing after treatment. Currently, the extraction method is mostly an open device, in which a conical flask is placed on an electric heating plate and a condenser is connected to the conical flask for reflux extraction. During the extraction process, heating may cause burns to personnel, and some substances evaporate into the air, causing pollution and human health problems.

[0003] To this end, the patent specification with publication number CN217528628U discloses an extraction device for testing the ion content of epoxy molding materials, including an extraction mechanism and a ventilation mechanism. The extraction mechanism is arranged inside the ventilation mechanism. The extraction mechanism includes an iron frame, a condenser, a conical flask and an electric heating plate. An iron frame is arranged on the upper part of the electric heating plate, condensers are fixed on both sides of the iron frame, and a conical flask is arranged under the condenser. The ventilation mechanism includes a fume hood and a sealed cabinet. A fan is arranged inside the fume hood, cabinet doors are arranged on the front and back sides of the fume hood, a grid base is arranged on the upper part of the fume hood, a sealed cabinet is arranged on the upper part of the grid base, a sliding window is arranged on the sealed cabinet, an extraction mechanism is arranged on the grid base, and a ventilation duct is arranged on the upper part of the sealed cabinet to solve the technical problems that the existing equipment has no ventilation device, volatile substances pollute the environment and easily cause harm to the human body, and there is no sealing device, which easily causes burns.

[0004] However, this extraction device for testing the ion content of epoxy molding plastics still has some shortcomings. First, it requires manual loading operation and cannot be automatically loaded, which cannot meet the needs of continuous testing of the ion content of epoxy molding plastics.
