Automatic optical inspection machine suppliers seem to tailor their machines for different tasks [eg, paste inspection, component ID & positioning, reflowed solder quality]. Is this observation accurate? If not, why? If so, what characteristics of

thanks for ur help. i would also like to know the classes is for showing different level of requirement, or for different vertical location of void in joint. coz I heard from my workmate that the range from 9% to 36% is for void at different vertical

Does anyone know of any studies that have been done on different types of thermo couple attachment? In particular I am interested in the temperature differences that are seen with the different methods of attachment.

i just thought that it because of difference thickness between the silkscreen and without silkscreen. if we apply the same pressure and dispense time to this two difference location, the glue size will be difference. location with silkscreen will rea

Yes, we use solder paste,solder bar and solder wire from different manufactureres for 1PCB assembly. And, what JAX said, we never mixed solder paste from different manufactures and used.

Probably just evolved - just different needs at different times. Back in the day for example there were lots of patents around turrets so different manufacturers went different ways. These have mostly run out now, so different technologies call for

Hi. Is there a difference between "centering a component" and "aligning a component"? I've noticed that "centering" is used much more often but I don't see any difference between "centering" and "alinging". Am I right?? As far as component feeders

Can anyone tell me the difference between the these 2 fluxes as i cant find a data sheet(i searched the alpha metals website) for the E191.I know the the 2 fluxes are both no clean but other than that?? The reason i ask is i found some E191 in our st

Well Dave, Check the number that is on your adhesive tube. They make several different types of adhesives for use on different substrates. The rep from Dymax recommended the 3073 for bonding to FR4. We use a Dymax HHL400 handheld curing light. Click

The best is, create 2 different profiles for each PCB type. Then segregate or separate them and do not let them run together in one line. Switch to the proper profile settings each time you change to other PCB type. This is the best. Each PCB materia
