Have you figued out how to import the gerber data into Camtastic? Once that is done click the tool menu at the top then the assembly utilities then create and group parts. This will allow you to select the pads for a given package and name it the

this is really nice one ;) paper and cotton have lowest potential to generate static electricity see below, and usually is good practice to wear cotton glowe at least to one of your hands to not leave greasy finger spots on the gold finish of the PC

I have previously experienced dispensing glue dots using a camalot system. This was used to dispense dots for a variety of components, as the SMT was applied post through hole and then wave soldered. No paste was used in the process. The other benefi

Hi Armando Hotflow 7 is a big machine and one of the best Reflow ovens around (in my opinion), well suited for Lead Free. A typical 1.6mm board has the following settings for Lead Free SAC305 paste All Temperature settings are Top and Bottom Prehea

We have been having problems with proper wetting when running mainly lead free but also leaded solder in our Ersa Hotflow 3. Solder either often looks grainy or doesn't flow over the whole pad. This is generally the case when my profile is 170 firs

Cause: Solder between the pad and the BGA on the pads being lifted has not melted. So, when you lift the BGA, you also lift those pads with the unmelted solder with the BGA. These pads are probably sinking the heat to a large copper plane in a inner

I have seen this problem before. There is a cable that runs from the Quadalign board to the backside of the backplane. It is not secured in any way so it may have come loose in shipping. Open the right side panel on the machine. The Quadalign board

Hi All, I see more and more components like QFN or LGA with bottom-only terminations,with landpatterns getting finer all the time. I have no ppm-figures of our process, but based on a benchmark study by Agilent I'd say that 500 ppm is a decent value
