The mass flow sensor, or air flow sensor is one of the important sensors of the electronic fuel injection engine. It is installed between the air filter and the intake hose to measure the intake volume of the engine cylinder and adjust the fuel ratio according to it. The mass flow sensor converts the inhaled air flow into electrical signals and sends them to the electronic control unit (ECU). As one of the basic signals to determine the fuel injection, it is a sensor that measures the air flow of the suction engine. So if you want to test it, how should you do? Let's start it.

Ingress Protection Test Chamber is used to determine the protection degree of product enclosures,the protection level provided by the enclosure is called IP code,our IP test chamber compeletely follow the standard IEC60529 and others. IP protection grade is an important index of electrical equipment safety protection. Protective-grade systems such as ip, which provide a method of classifying products in terms of dust-proof, waterproof and anti-collision levels of electrical equipment and packaging, which have been recognized by most European countries, as drafted by the International Electrotechnical Association (iec (international electro technical commission). And announced in ied529 (bs en 60529 / 1992) outer packing protection grade (ip code). The level of protection is expressed in terms of IP followed by two numbers, which are used to define the level of protection. The first number indicates the extent of the equipment‘s resistance to dust, or the degree to which people are protected from harm in sealed environments. I represents a level that prevents solid foreign matter from entering, with a maximum level of 6; The second number indicates the extent to which the equipment is waterproof. P represents the level of protection against influent and the highest level is 8. Such as the protection level of the motor ip65. Contact electrical equipment protection and external material protection level (first digit) Electrical equipment waterproof protection level (second digit) . IP is the international code used to identify the protection grade ip grade consists of two numbers, the first number for dust, and the second number for waterproof, the larger the number means the better protection level.

This paper will outline and define what requirements must be adhered to for the OEM community to truly achieve the IPC class product from the Electrical Test standpoint. This will include the test point optimization matrix, Isolation (shorts) parameters and Continuity (opens) parameters. This paper will also address the IPC Class III/A additional requirements for Aerospace and Military Avionics. The disconnect exists between OEMs understanding the requirements of their specific IPC class design versus the signature that will be presented from their design. This results in many Class III builds failing at Electrical Test... First published in the 2012 IPC APEX EXPO technical conference proceedings

This paper examines the potential failure mechanisms that can damage modern lowvoltage CMOS devices and their relationship to electrical testing. Failure mechanisms such as electrostatic discharge (ESD), CMOS latch-up, and transistor gate oxide degradation can occur as a result of electrical over-voltage stress (EOS). In this paper, EOS due to electrical testing is examined and an experiment is conducted using pulsed voltage waveforms corresponding to conditions encountered during in-circuit electrical testing. Experimental results indicate a correlation between amplitude and duration of the pulse waveform and device degradation due to one or more of the failure mechanisms.
