By "hacking" do you mean altering the performance of the board or something else? This reminds me of something I saw a while back. Better termed counterfeiting than hacking, it may have some relevance to what your friend is trying to do. The probl

To clean up other replys I will add that some most all machines have global correction. Most placements are an off sets from pcb 0,0 usually the lower left corner of the board. When the machine locates the fiduitals and these fids are not exactly whe

I agree with chuck, but would like to add. 2D is a great option and helps to keep your printing process in check, it will measure the x & y coverage on the pad. It will help you determin when your stencil aps become clogged or when the bottom of your

This string is near and dear to my heart and anyone who can simplify this process will be a hero. Our Production Lot Traveler started with the initial intent of being able to track lot splits (traceability) of jobs and who worked on them (accountabi

Particular as a small company and limited resources you�ll be requiring a lot of assistance from the machine vendor. Did you check which other machines are used in your area and if there is already a local service tech? Did you get in contact with o

Start with your board first. Do you have resist/mask between the fine pitch? Is the finish HASL or a flat surface? If there is no mask/resist between the fine pitch leads you may want to reduce the apertures 5%. If the board is HASL, that means yo

Sheldon, Tip life is directly related to temperature, IRON plating thickness on the tip, Alloy composition used and operator technique. High tin contents in lead free alloys attach the tips. Poor wetting and higher melting temperatures cause us

Sounds like air pressure is set O.K. The next thing to check is that the platen surface that the x and y axis ride on is perfectly clean. After that, you should knock the camera off the platen and make sure that all of the small air nozzles are blo

ICT is generally a manufacturing verification test. Coverages vary depending on the board. I've run lots with as low as 25% coverage on the board (but produced 98% FPY post board assembly). Functional test is exactly what it sounds like. Checking

Hi Steve-O, Good question(s). This process was set-up by an engineer that had a PhD in statistics, took him a year to develop and then thru it over the wall at us. The biggest problem we saw was SPC to measure solder volume. SPC is good for measu
