In general, failure of integrated circuits is inevitable in the process of development, production and use. Due to the continuous improvement of people's requirements for product quality and reliability, failure analysis is becoming more and more important. Through chip failure analysis, IC designers can find design defects, mismatch of process parameters, or improper design and operation problems. The following is a brief analysis of common ideas of chip failure analysis for your reference. View >>

RoHS directive originated from the European Union, with the rise of the production and use of electrical and electronic products (also known as EEE). During the use, treatment and disposal of environmental electrical equipment, harmful substances (such as lead and cadmium) may be released, resulting in serious environmental and health problems. RoHS helps prevent such problems. It limits the existence of specific harmful substances in electrical products, and safer substitutes can replace these substances. The following is a brief analysis of ROHS detection for your reference. View >>

Failure means that the circuit may fail, thus affecting the normal operation of the equipment. Most failures in electronic equipment are caused by the failure of electronic components. Electronic components mainly include components and devices. Electronic components are finished products whose molecular components are not changed during production and processing, such as capacitors, resistors and inductors. Electronic devices are finished products whose molecular structure changes during the production process, such as electronic tubes, integrated circuits, etc. View >>

In lead solders, lead exists as a basic element. In lead-free solders, the basic elements do not contain lead. With the strengthening of people's awareness of environmental protection, the use of lead in various industries is becoming more and more cautious. Among them, in smt chip processing, customers in different industries will be asked whether there are lead-free requirements for the welding process, which means that electronic manufacturing has very strict requirements for lead-free assembly process.
