Continuous Quality
PreventLab is by your side to help you avoid production line downtime with frequent quality checks on the most critical products. The Printed Circuit Board is the indispensable foundation of the electronic assembly; it is essential to ensure that the quality standards are as desired.
Verification of compliance with construction requirements according to IPC-A-600 LR Class 2, Class 3 standards along with technical specifications released by the customer.
Examination of the durability of the PCB even after multiple thermal stresses to simulate soldering phases and compatibly with the moisture absorption experienced by the product.
Assessment of the cleanliness level of the production line; the PCB production process is long and complex.
It involves the use of aggressive chemicals (e.g., plating baths) and mechanical removal of debris (drilling); therefore, if the product is not adequately cleaned, it may carry latent defects.
Analysis of the thickness and characteristics of the metallic and organic surface finish to ensure proper wettability and formation of the metallurgical joint.
Additionally, it is useful to evaluate the melting point of the tin alloy (HALS) to control potential copper contaminations.
