Webinar (2/18): "Visualization Solutions for Mold Interiors" in Semiconductor Resin Encapsulation and IoT Technology

Kistler Japan G.K. Head office

In this webinar, we will use CG videos to quantify the internal state of molds, often referred to as a black box, using the semiconductor encapsulation process as an example. We will provide detailed insights into the know-how for improving major molding defects and enhancing production processes. Kistler's piezoelectric pressure sensors are highly advantageous and optimal for the conditions of semiconductor encapsulation. We will also propose sensing technologies to improve major molding defects using piezoelectric sensors effective for low-pressure measurements, such as in epoxy transfer molding.

Visualization solution for the interior of molds in semiconductor resin encapsulation.
We propose improvements to the quality and production efficiency of package molding, where issues become apparent!

One of Kissler's core technologies is the adoption of a piezoelectric crystal in-mold pressure sensor, optimized for semiconductor resin encapsulation, with the following features: - Low viscosity resin compatibility ⇒ Structure that prevents measurement errors due to epoxy resin intrusion (diaphragm structure) - High-temperature compatibility for semiconductor resins ⇒ Mold temperature up to 200°C - Durability ⇒ Semi-permanent - Linearity (measurement error) ⇒ Guarantees less than 1% for the measurement range - Resolution ⇒ 1/1000 MPa The "visualization of the inside of the mold" in semiconductor resin encapsulation is a proposed solution to challenges arising from recent demands for miniaturization and thinness in semiconductor packaging. In particular, the rapid expansion of electric vehicles (EVs) has increased the demand for power semiconductors for automobiles, making the improvement of quality in resin-encapsulated packages, as well as enhancements in production efficiency and inspection costs, significant challenges. In addition to traditional software-based flow analysis, measuring and quantifying the in-mold pressure and temperature within the mold cavity using sensors has been recognized as an effective solution, and its adoption has already begun in actual manufacturing lines.
Injection Molding Internal Pressure Monitoring System ComoNeo 5887A
An innovative user interface combined with a capacitive multi-touch monitor achieves top-class efficiency and ease of use!

ComoNeo is designed to meet the requirements of the plastic injection molding process and the needs of operators in the manufacturing environment. An innovative user interface combined with a capacitive multi-touch monitor achieves the highest efficiency and ease of use. Additionally, the hardware of the device is designed with functionality in mind, allowing connections to be divided into the mold side (connected to the injection molding mold) and the molding machine side (connected to the injection molding machine or robot, extraction device, and other ancillary equipment). On the mold side of a single ComoNeo device, it is possible to connect up to 32 in-mold pressure sensors and up to 16 mold surface temperature sensors (using thermocouple temperature amplifier model 2205A...). The molding machine side is equipped with 12 digital inputs and 24 digital outputs. Furthermore, ComoNeo can record and analyze four analog machine signals (screw position, injection pressure, etc.). Smooth data transfer is achieved through USB and Ethernet interfaces, allowing visualization and configuration of ComoNeo using shared notebooks, PCs, tablets, smartphones, and other devices on the network.

Connect to the process monitoring system ComoNeo with a single cable! Space-saving! Reduced mold installation time!

The multi-connector models 1722A4... and 1722A8... save space within the mold and reduce the time required for mold installation through simplified connection technology. The multi-connector is used for connecting single wires and coaxial cables, making the installation of in-mold pressure sensors easier. The multi-connector simplifies and standardizes connections to in-mold pressure monitoring systems like ComoNeo. It prevents mix-ups when connecting sensors to ComoNeo, and an IC chip built into the multi-connector assigns specific molds, allowing ComoNeo to identify the connected mold.
