Hi all, I want to know the possible causes of poor paste release in stencil printing process if the same brand and part number of solder paste that has been used successfully is being used with a set of process parameters which worked before. Other t

No, there are no issues with mixed lead / no-lead post-reflow cleaning. No-lead is a little harder to clean so be sure you use the appropriate parameters and cleaning chemical. The only potential issue is if you mix up the boards after cleaning,

thank you for the reply.....this reinforces the same info about SAC305 that i had reviewed in other papers. Since this is an inherent property of SAC305, i am assuming 1. Wave parameter (temp/time) tweaking will not mitigate this? 2. what is differ

Hallo all, I have recently had possibility to work with DEK265. I have met with problem poor print definition (no sharp edges). I used stencil 150 thickness, metal squuegees. I moved than the same stencil, squeegee and parameters to DEK nifinty and

Hi People I will need some help on basic things really, we are replacing the existing solder pot with a lead free capable solder pot, but what are the other parameters that we need to look in to, to be able to achieve good quality soldering on the sa

We have a new SMT line, our customers are asking us the validation of the process. Not only the validation of the resulting assembled board (solder joint...) but also a validation of every single machine in the line (ex. stencil printer...). For exam

Hi, sounds unusual if your profile is accurate that you have so many residues. Had a similar problem before with no clean flux and with various flux manufacturers, and all residues were down to excess flux. This does not help your case though. How a
