Passed LGA factory inspection

Introduction: The "LGA qualified test" mark indicates that the product has passed tests conducted according to certain requirements (performance, safety performance, and other relevant legal requirements) and meets the current technical standards.
Manufacturers who want to obtain the "LGA Test Qualified" mark must pass the corresponding assessment according to the above requirements. To ensure the validity of this mark, LGA will conduct annual factory and product inspections on certified companies.
LGA passed the test: Electromagnetic compatibility (EMC)
Introduction: Our electromagnetic compatibility (EMC) mark certifies that the product complies with the EMC Directive and the relevant technical safety requirements of the German Equipment Product Safety Law (GPSG). LGA will regularly supervise and inspect the certified companies.
Quality certificate introduction: LGA quality certificate certifies that the product has stable and excellent quality. This mark confirms the safety (such as electrical safety, hazardous substances, etc.) and reliability (such as functional characteristics, loss, service life, etc.) of the product. Therefore, it is a comprehensive quality certification. Annual production supervision ensures the long-term stable quality of the product. As long as you see the LGA quality certification mark on the product, you can rest assured: these products have passed comprehensive testing.
LGA qualified: German Food and Daily Necessities Law Introduction: The "German Food and Daily Necessities Law" certification mark indicates that the product complies with the requirements of the German Food and Daily Necessities Law (LFGB). Every year, LGA will conduct supervision and inspection on certified companies.
Hazardous Substances Inspection Pass Introduction: With the "Hazardous Substances Inspection Pass" mark, manufacturers have a textual basis to prove that their products meet the minimum legal requirements (such as hazardous materials regulations, chemical bans), and also prove that they meet other LGA testing requirements for hazardous substances. In addition to basic testing and compliance testing, LGA will also conduct supervisory inspections on certified companies every year.
Introduction to CE-marking: The CE-marking (Communauté Européenne) indicates that the product meets the minimum requirements of the relevant EU directives. Whether the product is produced by an enterprise within the EU or a non-EU enterprise, as long as it falls within the scope of application of the EU directive (such as toys), it must be affixed with the CE-marking. Enterprises can conduct compliance assessments themselves (manufacturer's self-declaration of conformity) or through an authoritative testing agency (CE0125 = LGA). The CE-marking is a compulsory certification mark designed to simplify the procedures for free trade of products within Europe. It is not a product quality inspection certificate. Voluntary inspection marks, such as the LGA quality inspection qualified mark, are the marks that prove the quality of the product.
Microelectronics: Land grid array (LGA)
That is, the bottom surface of the package is made with array-like flat electrode contacts. It can be inserted into the socket during assembly. Currently, ceramic LGAs with 227 contacts (1.27mm center distance) and 447 contacts (2.54mm center distance) are in practical use and are used in high-speed logic LSI circuits.
Compared with QFP, LGA can accommodate more input and output pins in a relatively small package. In addition, due to the low impedance of the lead wire, it is very suitable for high-speed LSI. However, due to the complexity of socket production and high cost, it is basically not used now. It is expected that the demand for it will increase in the future.
