The automatic stencil wiper the first line of defense. Topics are: • The Printing process and why we need to focus on the wiping function • Frequency of wiping • Wiping options • Wiper profiles • Event driven wiping • Advanced options • Materials: Paper • Materials: Solvent • Preventive maintenance • Random stuff
Solder paste screen printing is known to be one of the most difficult processes to quality assure in Printed Board Assembly (PBA) manufacturing. An important process step in solder paste screen printing is the under stencil cleaning process and one of the key materials in this process is the cleaning paper1. This, often neglected, material affects the cleaning process and thereby also the print quality. It is therefore important to perform tests of different cleaning papers before one could be chosen. This article describes how cleaning papers can be tested and it also tells how big differences it can be between different materials.
The effectiveness of cleaning stencils and misprinted/dirty printed circuit boards can be effectively monitored. This can be done by washing known clean circuit boards and then checking to see if they have stayed clean as a result of the washing process.
Mydata Error Messages -- I just received the following messages while running our MY15: I-OSM-0: my15n150 kernel: lp: no devices found. I also received this one: I-OSM-0: my15n150 insmod: /lib/modules/.2.20/misc/lp.o: init_module: Device or resource busy. And this one: I-OSM-0: my15n150 insmod: /lib/modules/2.2.20/misc/lp.o: insmod char-major-6 failed. What does that mean? I cant find references to it. I assume they must be related. Can someone help?
