Ultrasonic Soldering and Bonding Ultrasonic Soldering and Bonding - Active Solder - Sonic4Lab Soldering is similar to welding. Soldering is a welding method that uses low melting point metal solder to heat and melt, and then infiltrate and fill the gaps at the joints of metal parts. Ultrasonic soldering iron is usually used for soldering. Ultrasonic Soldering and Bonding System is mainly used for soldering materials and has advantages such [...]

What Industries are Ultrasonic Soldering Applied in? What Industries are Ultrasonic Soldering Applied in? Sonic4Lab In the fields of electronic manufacturing and metal processing, we often need to put a thin "tin coating" on metal components - this process is called "tinning" or "tinning". The purpose is to improve the weldability of the metal, prevent oxidation, or prepare for subsequent welding. However, a common challenge lies ahead: most metals quickly [...]

Ultrasonic Soldering Battery Module Ultrasonic soldering battery module: industrial path and reliability verification to reduce backside silver consumption by 40% In the rapid development of the photovoltaic industry, the sustainability of materials is becoming a key challenge in achieving the goal of fully renewable energy. Among them, the consumption of precious metal silver is particularly prominent. Especially in the current mainstream double-sided PERC+solar cells, silver is not only used for [...]

Ultrasonic Soldering and Bonding Equipment Ultrasonic Soldering and Bonding Equipment - Sonic4Lab What is ultrasonic soldering? Ultrasonic Soldering and Bonding Equipment is a disruptive flux free welding technique that has been used for connecting difficult to solder materials such as aluminum since the 1950s. It is based on the cavitation effect caused by high-frequency vibration (usually 20-30 kHz), which can remove the surface oxide layer of the material without the [...]

The Truth About Gold-Plated PCBs: Easy Soldering Among PCB surface treatments, immersion gold is highly sought after for its long-lasting properties, smooth pads, and excellent solderability. However, its high cost deters many. Many believe its solderability is due to the gold coating, and even believe that the thicker the gold layer, the better the soldering. This is a misunderstanding. The truth is, the excellent solderability of gold-plated boards isn't due [...]

Can Vias be Drilled Through Pads? In PCB design, whether vias are necessary depends on the specific scenario and process. In some cases, drilling vias through pads is necessary. For example, to improve heat dissipation for large devices like MOSFETs, vias are often drilled on the backside of the pads. In this case, the holes should be evenly spaced to ensure uniform heating. However, the biggest problem with this approach [...]

A Critical Step in PCB Copper Fill Design A Critical Step in PCB Copper Fill Design - Ultrasonic Soldering Lab Trials - Sonic4Lab In PCB design, copper fill is a crucial step in covering unused areas with copper, significantly impacting circuit performance. Its core functions include reducing ground line impedance to enhance anti-interference capabilities, reducing voltage drop on power supply lines to improve efficiency, and reducing loop areas by connecting [...]

Ultrasonic Soldering Iron Soldering PCB Gold Fingers Ultrasonic Soldering Iron Soldering PCB Gold Fingers - Sonic4Lab In electronic product interconnect systems, gold fingers are specialized connectors. These are gold-plated pads located along the edge of a PCB, named for their finger-like shape. As connectors between the PCB and the motherboard, gold fingers not only ensure reliable signal transmission but also protect the edges of the circuit board from damage. The [...]
