Most of the problems that you will find with NC is visual. I have not found or heard of any real evidence that NC causes component or board failures. The residue has extremely high resistance, which actually gets higher as time goes on. It's a paradi

I can only describe how the Grid Lok handles component variability. The compliant caps have an annular ring that is very soft and can mold to different shapes. If a component shows up where there was no component before, the outside of the cap bend

Jim, I wouldn't sweat a TCE mismatch between Ceramic chip components and FR4. No need to worry. 99.5% of consumer product out there utilizes this exact technology with no threat of failure due to CTE mismatch. The terminices of the components occu

Rick, Does the ultrasonic cleaning system that you use reuse the same water for each cleaning cycle? I have had a similar problem in the past using a Brandson ultrasonic cleaner and water soluable flux. The problem was the buildup of flux in the clea

I don't know what type of boards you are doing but if they are through hole or surface mount. You can get a whole line of used equiptment for pennys these days. I am sure that I could send you a quote for a complete line. The price of used equiptment

Hi Jeff Actually it's not necessarily Signal to Noise Ratio or even RF circuitry. All no cleans leave behind residue by description. This residue can affect RF or other high frequency circuits in a number of different ways including SNR. Very high

I am researching a process call Collumn Grid Array for the BGA. Please email me if you have some knowledge about this process. The problem is ceramic BGA has different thermal coefficient with PCB (FR-4) material, and in extreme temperature (-40 C-

I have 2 SMTech Sigmaprint 400s. They are easily the best screen print buy for the dollar. They perform like machines costing 50K more. They are probably the best kept secret in printing. My machines are 16 mil. capable, can be optioned to go bey

| John, A year ago we did a serious market analysis prior to purchasing a couple new machines. We looked carefully at the same machines that you did and settled on the Philips Orion and Philips Eclipse. We have had the machines online for a year an
