Before you worked in FPC Industry, you have just transferred to touch industry. Now you are engaged in printing technology. Now there are a few problems, let me have a headache, also ask all the immortals to give little brother advice!）S / a # L R3 question 1. Because my younger brother only used FPC printing silver paste, which was only used for the shielding layer of mobile phones, the screen printing was block printing, so it was relatively simple. But now we need to print the circuit with silver paste. I tried to test it with the parameters and experience of FPC, but the effect is not ideal. There are many broken lines and gaps. What kind of parameters should I use to optimize? (Far East CCD printing press used now)2. After printing, I used a washing water used in other processes to wipe and clean the screen, but this washing water is very poor. Every time the screen and steel mesh can't be washed clean, resulting in plugging of the screen, and the air gun can't blow through the holes. Two screens and one steel mesh have been scrapped because they can't be washed clean (very depressed), I have applied for anti white water by myself, but I haven't tried it yet. Do you use anti white water? In fact, there is a better water for washing the net. I can recommend it to you. Your Q number is 412099614. I hope you can find a master to support you in this industry. Hehe, I'm a blacksmith. I can't help you....... Are there any great immortals and gods. I don't want to go down. Brother and the second floor are colleagues, there is nothing we can do.
