hi We start to make a product which have a 0.4 mm pitch IC and start having problems with not enough solder printed, to solve this problem we had to increase the manual cleaning, now we are cleaning the stencil every 8 printings, before we was running models with 0.5 mm pitch IC's without any problem (cleaning stencil every 15 pcb's) Do you have any recommendation about solvent to clean the stencil, right now we are cleaning with regular alcohol ? We want to reduce the printing defects and reduce the manual stencil cleaning frequency.
I will appreciate your support.
