We constantly see unsolicited emails from companies in China. One is "JSD PCB", the other is Ideas PCB. JSD will send you an email which is designed to make it seem that you contacted them first. Ideas PCB sends the same email, but with a different reply email address. Lennard Electronics sees this practice as very very unprofessional, and we will not engage in any business with such organizations, and advise you stay clear of the likes of these organizations as well. We are also disappointed that their selfish behaviour puts a bad mark against the otherwise honest and good folk of China, preventing business opportunities.
