Hello Had a similar problem way back with the hydra, first go to the service program manually activate the hydra camera then move the Xwagon to place the hydra ref plate over the hydra camera and check first if the camera works, second the image you

Hi I have been having a problem with my Hydra tool reference plate. Machine keeps stopping and comes up with error message - failed to locate hydra tool reference marks & Error mounting component .... from feeder ..... with nozzle .... I have check

It's been long time, me memories are fading away. If I remember correctly, you would need small flat surface plate or something to cover up the "linescan" hydra camera, so from the reflections value then it can calculates the actual height "lowest"

Chemical gold is a poorly defined [very sloppy] term that means various thing to different people [as you've demonstrated]. Commonly it is either: * ENIG: 5�m Ni, 0.1�m Au * Immersion gold "Autocatalytic chemical gold plating" - Refers to "electrol

Hi Peter, The defect you observe during the second side reflow could be caused due to improper Au plating thickness in the PCB fabrication process. You can refer IPC-2221 wherein plating thicknes for ENIG mentions 0.08um to 0.23um for Immersion Gold,

Check the reference plate on the hydra to make sure it is not cracked or delaminated. I have had problems with the glue coming loose and the plate flapping causing this same problem. check hydra camera calibrations, this to may help.

Hi Adam, I would suggest you refer IPC-2221 guidelines which define plating thickness as: Nickel 2.5-5.0 um , Gold 0.08-0.23 um. Although ENIG is a standard process, there is an associated risk towards Gold embrittlement, Porous Gold, or Black pad de

Flash gold usually refers to electrolytic gold with a short plating time. In other words gold plating that requires current to plate. If you have bare copper under your soldermask, the gold is probably ENIG. The only other way to have bare copper

We recently ran into a situation where a SMT header with tin plated tails would not wet properly during reflow. Someone told us that tin plating has a shelf life and needs to be re-tinned after a length of time. I have not heard of that before. Do
