The following infromation has been received,but our company has the following problems and need your help.1.All of the materials we named as English material name, but we have not received any request for name modification of other materials.So I can understand that the names of other materials not mentioned are correct,right?and how should I understand the descriptive material names mentioned below,for a example, Cathode foil, named A1N90H ?2. Our SMD products use pet coated aluminum alse,which contains PET in its composition, so we called it PET(al case).
