What is Countersinking? Countersinking is a machining process where a conical hole is cut into a manufactured object, or hole, to allow the head of a countersunk bolt or screw, when placed in the hole, to sit flush with or below the surface of the surrounding material. A countersink may […]

Understanding Solder Escape and Its Causes Solder escape, also known as solder wicking, is a common issue faced during the reflow soldering process in PCB Assembly. It occurs when molten solder flows or “escapes” away from the intended solder joint, often along the component leads or PCB traces. This unwanted […]

What are Fiducials in PCB Assembly? Fiducials, also known as fiducial marks or fiducial points, are small, precise reference marks placed on printed circuit boards (PCBs) to help align and position components during the assembly process. These marks serve as visual cues for automated assembly machines, ensuring accurate placement of […]

What is Metallization? Metallization is the process of coating a non-metallic substrate, such as plastic, ceramic, or glass, with a thin layer of metal. The Metallization Process involves depositing a thin film of metal onto the surface of the substrate material to give it metallic properties such as conductivity, reflectivity, […]

Understanding the Basics of Spring-loaded Pins Construction and Working Principle Spring-loaded pins consist of three main components: a plunger, a barrel, and a spring. The plunger is a movable pin that protrudes from one end of the barrel and is designed to make contact with the mating surface. The barrel […]

Introduction to Audio Delay Circuits An audio delay circuit is an electronic device that creates a time delay in an audio signal. By delaying and feeding back a portion of the audio signal, delay circuits can create echo, reverberation, chorus, flanging, and other time-based effects that add depth, spaciousness, and […]
