What is the best solder paste to choose for AI chip packaging?

In AI chip packaging, the selection of suitable solder paste needs to take into account the chip power density, packaging process, reliability requirements and thermal performance.

What Is Black Pad?

Copper is commonly used as the pad material in the packaging process. To avoid copper oxidation and improve the solderability of copper pads, various surface treatment methods are used to coat metal layers on copper pads. Common surface treatment processes include OSP, electroless nickel immersion gold (ENIG), etc.

Wave Soldering Solder Pull Tip is How to Form

Wave soldering, sometimes found at the top of the components and pins or solder joints with icicle or stalactite-like solder, this phenomenon is called pull tip, as shown in Figure.

The principle of anisotropic conductive adhesive in detail

Anisotropic Conductive Adhesive (Anisotropic Conductive Adhesive, ACA) is a special kind of conductive adhesive, its conductivity has a directional, that is, after hot pressing and curing in one direction (usually vertical) with good conductivity, while in another direction (such as the horizontal direction) is manifested as insulation.

What is the difference between solid crystal solder paste and red glue?

Solid crystal solder paste and red glue are two common materials in the field of electronic packaging, and they have significant differences in composition, function, process, performance and application.

μBGA, CSP in the Reflow Soldering of the Reasons for the High Rate of Cold Soldering

In the reflow soldering process, for μBGA and CSP packaged chips with dense feet (pitch ≤ 0.5mm), there is a risk of higher incidence of cold soldering due to the hidden nature of the soldering site and the difficulty of heat transfer to the solder ball solder joint site. Under the same peak temperature and reflow time conditions, the heat gain

The Introduction of IoT

When you start your day, the alarm goes off, and the coffee maker starts brewing. The lights come on as you walk through the house. Some invisible computing device responds to your voice commands, reads your schedule and news, and turns on TV news when you're ready. Your car will drive you to work through the least congested routes, allowing you to
