PCB Warp Measurement Method: Measuring How Flat It Is Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB warp measurement method gives you a practical advantage…

PCB Bake Before Assembly: Driving the Damp Out Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB bake before assembly gives you a practical advantage when…

Medical Grade PCB for Sterilization Equipment The Equipment and What It Does to a Board Sterilisation equipment exists in several forms, and each one attacks electronics differently. Steam autoclaves run saturated steam at 120 to 135 degrees Celsius and then cool, so the board sees repeated temperature cycles with condensation…

PCB Vibration Test: Shaking the Board to Find Weakness Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB vibration test from the perspective of a PCBA factory floor,…

Ultrasonic Sensor Module PCB Design Why the Board Decides the Accuracy An ultrasonic ranging module transmits a burst of sound, waits for the echo, and converts the round-trip time into a distance. The transducer gets the attention, but the measurement is won or lost on the board. The transmitter must…

Wire Bonder Control Board: Design and Manufacturing The Board That Decides Bond Quality A wire bonder places a wire a few tens of microns across onto a pad, forms a bond with force and ultrasonic energy, and does it again several times a second for hours. The control board is…

Flight Data Recorder PCB Assembly What the Board Inside a Recorder Does A flight data recorder is built to keep recording when everything around it has failed, and the board inside is designed to the same expectation. It collects data from the aircraft’s buses and sensors, conditions and filters it,…

PCB Thermal Shock Test: From Hot to Cold in Seconds Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for years. This…

PCB Humidity Test: Living in Damp Air Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for years. This article explains PCB…

PCB Temperature Cycling Test: Heat and Cold, Again and Again Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for years. This…
