Solder paste is an essential material in the process of soldering components and SMDs (Surface-Mount Devices) onto printed circuit boards (PCBs). How is this material used? Let’s explore the concept of solder paste, its proper storage after opening, and its components in this article. What is Solder Paste? Solder paste, also known as tin solder […]

Temporary masking materials are often used to protect the surface of electronic circuit boards from damage during coating and processing. These materials are characterized by being non-polluting, non-flammable, and leaving no corrosive or ionic residues. To better understand what temporary masking materials are and the common types available in the market today, let’s dive into […]

Electron microscopes are frequently mentioned in the context of observing objects by magnifying images multiple times to clearly display extremely small items. This device is primarily used in laboratories for inspection and repair. To understand what an electron microscope is, its structure, and its applications, let’s delve into the article below! What is an Electron […]

Solder flux is an active substance commonly used in electronic circuit soldering. So, what is solder flux? What is its composition? Is solder flux toxic? Let’s explore more about this substance in the article below with Hapoin! What is Solder Flux? Solder flux is a chemical primarily composed of a mixture of rosin, which aids […]

In diaphragm pump products, the ability to pump high-viscosity liquids is often mentioned. So, what is viscosity? How does it affect the performance of the pump, and what applications does it have in various fields of life? Today, Hapoin will help you understand this better in the following article. What is Viscosity? Viscosity, also known […]

Industrial oil or hydraulic oil has a very important property, which is viscosity. The particles in fast-flowing streams will impact the slower particles, increasing kinetic energy or inhibiting movement, thus creating internal friction. Today’s article will help you understand what kinematic viscosity is, its meaning, and its applications in real life. What is Kinematic Viscosity? […]
