Understanding PCB Deformation and Its Impact on Electronics Manufacturing Printed Circuit Boards (PCBs) are the backbone of modern electronics, providing a platform for interconnecting electronic components in a compact and efficient manner. However, during the manufacturing process and throughout their lifecycle, PCBs can experience various forms of deformation, such as bowing and twisting. These deformations can have significant implications for the functionality, reliability, and longevity of electronic devices. In this article, we will delve into Read more…

Understanding OSP PCB Surface Finish OSP is a chemical coating applied to the exposed copper pads on a PCB after the etching and plating processes. The organic compounds in OSP form a protective layer that prevents the copper from oxidizing and maintains its solderability for a limited period. Composition of OSP The composition of OSP varies depending on the manufacturer, but it typically includes: Benzimidazole derivatives Azole compounds Additives for improved performance These organic compounds Read more…

Understanding Surface Finishes in PCB Manufacturing Surface finishes are critical in PCB manufacturing as they protect the exposed copper pads from oxidation and contamination. They also enhance the solderability of the pads, allowing for proper bonding between the PCB and the electronic components during the assembly process. There are various types of surface finishes used in the industry, each with its own advantages and disadvantages. Some common surface finishes include: Hot Air Solder Leveling (HASL) Read more…

Understanding Solder and Its Composition Solder is an alloy, typically composed of tin (Sn) and lead (Pb), although lead-free alternatives are increasingly common due to environmental and health concerns. The specific composition of solder can vary depending on the intended application and desired properties. Common Types of Solder Lead-based Solder: Tin-lead (Sn-Pb) solder is the most traditional type, with a typical composition of 60% tin and 40% lead (60/40). Other common ratios include 63/37 and Read more…

Composition of Solder Paste Solder paste is made up of two main ingredients: Solder alloy powder Flux medium Solder Alloy Powder The solder alloy powder makes up 80-90% of the paste by weight. It consists of tiny spherical particles of solder, typically a tin-lead (SnPb) alloy or lead-free alloy such as tin-silver-copper (SAC). Common solder alloys used in paste include: Alloy Composition Melting Point Characteristics Sn63/Pb37 63% Tin, 37% Lead 183°C Eutectic, good wetting, low Read more…

What Causes PCB Delamination? There are several potential causes of PCB delamination: Moisture Absorption One of the most common causes of delamination is moisture absorption by the PCB substrate material. FR-4, the most widely used PCB substrate, is somewhat hygroscopic and will absorb small amounts of moisture from the environment over time. If the moisture content becomes too high, it can vaporize during soldering operations. The rapid expansion of water vapor can cause localized delamination. Read more…
