We are running Clean process. solder beadings were found after the wash process. Weird eh!! It's true.. Details: 1)wash pressure ? No shadowing effects from high profile component. It also happened on the component's body of the 1210 & 0402 caps whi

Thanks for the reply,Yes the data should show the yield difference from Paste printing process to wave solder process.I mean if we have Low yield that means more rework in that Case-Thanks & looking forward to get more information Surinder

Dear All, I am a totally new to the SMT process. In fact, I just had an overview course regarding the whole process of PCBA manufacturing and I have know a bunch of questions in my head. Most of them are linked to the solder paste printing process

Is somebody has Comparison data between SMT Glue & Solderpaste process.I know,the paste printing process is better to achieve high yields,but I want to see some Comparison data in terms of rework.

7mm FOV with graduations of 0.05mm. They'll cost around $100 - $150. Fun for measuring other "stuff" as well. Enjoy yourself amigo and you're right, printin' is REAL important.

When you ask for data in terms of rework, do you want reflow solder yields versus wave solder yields? Or do you want repair data from each process, or yield data that shows actual glue defects from screen printing versus solder paste screen printing

Can you use the equipment manual as the basis for learning how to use the machine? Each model of printer has different alignment techniques. We don't have a clue of your model type. So, we'll approach the question from its most basic point. Registe

About the automated printing machines: They are all a little different, but the alignment part of the process is basically the same. I don't know if you have ever seen an automatic printer, so I'll do my best to explain it. The PCB rides into the

Hi, I need some urgent informations on stencil design guidelines on how to perform epoxy printing on 0603 and 0402 components. Could anyone help? ( Reflow process is not possible because of some other constriants) Secondly, I need also facing a lo

Hi MPMENG, Thanks for you reply. I must say I am printing onto wafers& I'm still somewhat new to the process but much of the theory is the same as for PCB. I trialled it in the mean time and I did find that printing into the long side of the pad wa
