6 deg is std angle. Some machines have option to adjust angle from 5 to 7. Maybe yours does. If you have an Electrovert wave machine you can get the Omega option. This option vibrates the wave to reduce surface tension. It does a nice job on rectangu

I was using a combination of Alcohol and then compressed air for a while because I didn't wanted to add new hazardous chemicals into my factory but after looking into Vigon SC200 with a H/F/R of 0 I decided to try it. Since I started to use it, my

AJ: Problems with IPA are: * IPA / material being 'cleaned' combination still needs to be removed from the stencil. * IPA and empty containers are a hazardous material by RCRA criteria (40CFR 261) * Flash point (~12*C TCC) of IPA is low enough that a

Hi CW, Larger chip caps can be susceptable to cracking, but mainly this is due to handling - flexing of boards is the main culprit (the part being mechanically joined at both ends to the board). PCB's usually flex easiest along one axis, and larger

Ken, It happens about two or three times a month on my shift. I am sure that it happens on other shifts as well. I have not even bothered sending the status to Mydata. I have a difficult enough time getting answers on things "out of the norm" from B

I don't want to throw a spanner in the works here, but a large proportion of chip resistors & capacitors have been ROHS compliant for a couple of years now, the manufacturers have just not declaired it. Could it be that the part you have just has

Try using a contrast filter. This seems to help. Also on the camera it self there is a white level control. Adjusting this may help. The bad thing is it may affect all your other profiles. Some times an easy fix is to have a screen print mark close t
