the puspose of solder mask is to prevent exposure of cu tracks to atmosphere. the lesser thickness can effect the performance of board but it only depends on its application. if you are making telecom board then its not good to use the board.

Dave, you�re probably looking for a bar-code tracking system. Mydata actually has this function built into their software. You can search by part number and it will tell you even across multiple machine if your share info.

We have a problem with dendritic growth that is affecting a new board going into production. This is of concern because they were subjected to Damp Heat Cyclic Tests as part of the product validation testing during their development. Fails to date

Hi, How do you validate a pick and place machine's performance after installation? What standard will I use to track placement accuracy? what other factors do i need to look at? thanks and regards,

I need to load SMT tant. capacitors into sticks for a special placement application on a GSM for track presentation. Does anyone know a company that mfg's custom tubes/sticks for SMT components?

Hi Grant, You'll need to move the nozzle changer on your machine if you want to run very big boards, it comes out quite easily. (It's single track & not set up for RAM or PTIF, no shuttle & standard handling) Cheers, Rob.

Anyone come across pcb fab.house in Asia who is capable of doing 5mils track with 5% tol and 50 ohms impedence?

Oven runs, input/output sensors work but no product tracking. Various resets have no effect and cannot reset Drive Cycle Timer due to "not calibrated" error. Where can I find the procedure without manuals on-hand?

Has anyone tracked solder (Paste and or Bar) over the last 5 years. My company would like to see what the trend was, but we didn't keep records since we purchase from distributors.

Unplug light pen. Plug in mouse (track ball). Unless you've upgraded your idustrial PC you need to find a PS2 trackball
