355nm UV laser marking on IC package Josh, from the United Kingdom, purchased a batch of S9 UV lasers from RFH for IC package marking in October last year.   At the beginning of this month, during our after-sales return visit, Josh said that the RFH S9 ultraviolet laser has a very fine spot, and the marking effect is not easy to wear and fall off. It is several grades higher than ink jet coding, and the marking characters are clear and beautiful. It will not hurt the functional attributes of the package, can help him realize mass production quickly, and be compatible with products of different specifications. In a word, all words are favorable comment! !
