You wanted someone from Loctite to add their opinion on the matter. Our official statement on expired material is that after the expiration date we can not certify the performance and/or quality of the material. Although most likely the material is g

Considering only Ionic residues is very dangerous, most heat transfer fluids that are extremely hygroscopic are also non ionic especially those used in HASL / Roller Tinning fluids. Also consider if the resist is cured or in fact porous which absorbs

Hi Just one idea, many exist. If your electrical designers can tolerate it, sometimes a cross hatched design is used under areas where electrical performance is important. It reduces coupling and impedance effects compared to a full layer. Elimina

Large copper pours create an unbalanced lay-up that is bad design practice, creating problems in fabrication and assembly. The hatching a previous poster mentioned could be an alternative. Stepping back a bit and wondering, what's the problem? You

Hi I hear you, and you are right, yet most good process engineers strive to make future life a little easier by going back to the designers and making some alterations that don't affect performance. Now if we did a 6 sigma type analysis than this p

I work alone in my SMT department so I listen to whatever I want, and loudly. It helps me work I believe. BUT..... You have to take each case seperatly. I know some people I could trust to do a good quality job while asleep. But then you have those t

Hi Gee I am going to have fun with each of these messages. Thank goodness you are alone, and maybe you are able to use the tempo of the music to speed up your work or create greater concentration. I know it can happen. And then you probably turn of

Good Day, We have been searching for ways to do this very thing. We have sent them out for cleaning in hot baths, ultrasonics, pressure wash, etc... The chains have come back cleaner than they left but not perfect. At one point, one of our engineers

Scott, We have 2 Amistar Placepro 5620's and 2 5720's. One with a TF-14. I've personally been working on these for the past 10 years or so. Have a pretty good grasp of the process, if placepro's are what you are using. Glad to see Amistar is
