In case of pure pattern recognition, i agree with your view. However, the basic functionality of the fiducial is determine any positional offset of the PCB and provide necessary data for correction during the intended operation such as Paste printing

You should definitely profile your new BGA containing PCB with a real profiler with attached thermocouples. I would actually drill a hole under the BGA and put a thermocouple there.BGAs usually require longer profiles with longer soaks zone.....and s

Generally, that should not be a problem. Software for this purpose is pretty simple, the main issue is how accurately pcb carrier will be positioned at both ends. This is purely dependent on printer's mechanics. I have an old DEK247 and thought about

Rob, I have done it different ways. For the centroid you can do offline CircuitCAM or Valor or even pure Excell. I have used even pick and place machines files to extract data for AOI/SPI programming. These locations and coordinates are already there

Hello, I would lke to ask you about one issue. I am finding maximal level of impurity in solder pot with solder Sn99Cu1. I have limits for pure (delivered) solder, but I can not find limit for solder in pot in process. Could you help me where I can f

as its a customer product we cant change much of the process. the pins have gaps on them to allow for out gassing. its purely gravity when the solder is liquidous i believe. need a carrier as you say or a type of adhesive to hold them down. do you kn

What about nitrogen purity? Erza won't say anything other than you need 99.999% pure nitrogen. We are looking at another company that says the same. At a previous place we switched from dewers of liquid nitrogen to a single pass filter. I could see

What you are most likely dealing with: Insufficient Pure Sn layer ( multiple causes ) Because elevated temperatures accelerate the diffusion process, the thickness of the Pure Sn layer will reduce during every thermal cycle... ( bakeing PCBs, S
