I'm doing some research into some various costs for defects and work stoppages in an SMT environment. Specifically, I'm interested in what are the costs for a company to rework defective boards...from easiest to hardest component but not to include c

The issue of using ultrasonic technology for post reflow de-fluxing presents challenges in two categories: Controversial: Although there are recent studies that indicate acceptance with ultrasonic technology on populated assemblies, there remains si

Problems using NC in RF circuits are peculiar. Depending on the situation [ie, circuit layout, frequency of use, processes used, materials, and what not], a particular NC flux may not work with a RF circuit. Various NC fluxes leave different levels

Does anyone know of a No Clean solder paste that works well with RF boards. I have tried no clean in the past, and the boards have failed miserably

Everything we do is RF and have had no problems in the last 7 years with - Indium NC-SMQ92J, Sn63 Pb 37, 90.25% Metal, -325+500 mesh. Stencils are always 0.005" thick. However I will qualify that by adding we are an OEM and each new product may requi

We currently have a requirement to build flexi circuits and mount two 40 way, 20 thou connectors at each end. The flexi pcb's arrived in singlulated format. Ideally we would like to have the circuits panelised for machine building as hand placing the

To me the most challenge would be the printing step. If you can print it, you should able to run it with SMT. We ran similar thickness flex boards before. But it's long flex with small stiffener at both ends, and it was 10up array. You need fixture

Hi, I curently have an interesting challenge. But I don't have all the knowledge to solve it. One of our boards is used in RF applications. We noticed that the No-Clean flux residue makes interferences in the RF signal. Removing the flux residue so

Hi Joe, I work for an equipment manufacturer and we have processed RF housings before so I know they are challenging in terms of thermal mass. Let me know if you are available to discuss your application details and what would be a good email addre
