WE HAVE A NEED TO BOND SOME LOW TEMPERATURE LED'S TO A THIN CIRCUIT BOARD LAMINATED TO A HEAT SINK. HAS ANYONE USED AN ULTRASONIC WELDER TO WELD COPPER GUL WING LEADS TO A COPPER PAD USING ULTRASONICS? IF NOT HAS ANYONE USED RESISTANCE SPOT WELDING

Rick, Ultrasonics can damage some components that react to the mechanical action of the ultrasonics inside the device. Some component mfr data sheets will comment on ultrasonics. Better safe than sorry. Dean makes a good point if you can change so

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

Hello Does somebody of you have some experiences with ultrasonic detectors in SMT-Production? Is it possible to test quality of solder joints by using a ultrasonic detector similar to non destrucitve crack inspection tests? Is there a manufacturer fo

have you tried using an ultrasonic cleaner? i heard this from a friend and told me about this option. although, you may have to use a solution with the machine. here's a link i saw before while researching on using ultrasonic cleaner for pcb: http:

Have you tried an ultrasonic water cleaning process? We use an ultrasonic cleaner with tap water and Omega Aqua Clean LPH cleaner (omegasonics.com) then rinse with DI water. However, our cleaning requirements are not as strict as yours are from the

You should check the archives, there has been much written on this subject in the past. Asking about the correct chemistry is wise. It never ceases to amaze me how many people think ultrasonics will work without the proper chemistry. Without the rig

Guo: You want to know: 1 Can I use water as the solvent in an ultrasonic machine to remove solder paste from PCB? Continuing from Jason�s comments: Sure you can use water as the solvent to remove solder paste from PCB, but recognize that some flu

JNJ Industries just came out with some real cool new chemistries for Ultrasonics at Nepcon called Aquasonic. You can contact them for info at 800-554-9994 | dear all: | we use the HCFC,manufactored by 3M,for the ultrasonic stencil cleaner.but it's t
