Diode Sintering Process and Packaging Fixtures
The Fundamentals of Sintering
Sintering encapsulation involves assembling relevant components into an electronic product, which is then passed to system or module manufacturers for use on circuit boards. Common electronic products include capacitors, inductors, diodes, transformers, relays, and integrated circuits. This article introduces the sintering fixtures for the [Crystal Diode] manufacturing process, an area where our company has extensive experience:
(1) What is a Diode?
Ans: Diodes are often represented by "D" plus a number in circuits, e.g., D5. The main characteristic of a diode is unidirectional conductivity, meaning current passes in only one direction. Under forward voltage, resistance is very low; under reverse voltage, resistance is extremely high or infinite.
(2) Where are Diodes used?
Ans: Due to their unidirectional conductivity, diodes are often used in rectification, isolation, voltage regulation, polarity protection, coding control, frequency modulation, and noise suppression circuits. For example: cordless phones. Different types include Rectifier Diodes (e.g., 1N4004), Switching Diodes (e.g., 1N4148), Schottky Diodes (e.g., BAT85), LEDs, and Zener Diodes.
(3) Diode Structural Types?
Ans: Based on encapsulation, they are divided into Glass Body, Metal Case, Plastic Case, and Epoxy Resin types.
(4) What fixtures are required for Diode Sintering Production?
Ans: Below we use [Glass Body] diodes to explain the fixtures needed in the sintering process.
Since leads, chips (dies), and glass tubes need to be combined during the process, factories producing glass-encapsulated electronics typically use the following fixtures and equipment:
A. Chip Shaker / Die Loading Tray: Selects chips of appropriate electrical properties and size based on the specifications of the glass electronic part. (This stage can also be done by automated equipment instead of manual shaking).
B. Lead Loader & Lead Feeder Box: Arranges leads according to length and size prior to loading into the soldering plate. (This stage can also be automated).
C. Glass Tube Shaker: This fixture arranges glass tubes based on size and length and assists in transferring them to the soldering plate.
D. Soldering Plate (Sintering Boat): Holds the various components in sequence for assembly and passage through the sintering furnace to complete the product.
The fixtures introduced above are essential for producing glass diodes. We hope this article helps you better understand your work and our expertise. Thank you!
