How to Store and Prepare Solder Paste Correctly – 8 Rules for a Stable SMT Process
High-quality solder paste is a precisely balanced system of metal powder and flux. However, formulation alone does not determine how reliably it will perform in an SMT process. Storage, temperature conditioning, and handling before use can also have a significant influence on processing characteristics. A solder paste manufactured and tested under controlled conditions can be […]
SMT Soldering Defects: Identifying the Causes and Preventing Them Systematically
A stable SMT process is the result of many carefully coordinated factors. Solder paste, stencil design, PCB condition, components, printing parameters, and the reflow profile all need to work together as one system. When defects such as voiding, solder balling, poor wetting, or tombstoning occur, the solder paste is often the first suspected cause. In […]
Recycled Metals in Solder Pastes – Sustainability Without Compromising Quality and Reliability
Sustainability is becoming increasingly important in electronics manufacturing. Companies are no longer focusing solely on the energy consumption of their production processes. Raw materials, supply chains, material origins, and the use of secondary resources are also becoming increasingly relevant. This is particularly important for solder pastes. A significant proportion of solder paste consists of metal […]
Choosing the Right Solder Paste – 7 Key Factors for a Stable SMT Process
Selecting a solder paste is often reduced to two basic criteria: alloy and powder size. In practice, however, these factors alone are not enough to ensure a stable and reliable SMT process. Solder paste is a sophisticated system consisting of metal powder and flux. Its performance must be matched to the specific requirements of the […]
Rising Silver Prices: New Momentum for Your Alloy Strategy
Rising silver prices are creating significant market movement and forcing companies to make new strategic decisions. Our application engineers are also closely engaged with these developments. In recent weeks, the focus of many customer discussions has shifted. While topics such as process windows, print stability, or profile optimization typically dominate conversations, one central question is […]
