| To all SiPlace Users, | | I know there are lots of you out there! From your own experiences, what sort of life expectancy would you expect (in terms of number of placements) from a rotary star head for a Siplace 80S15 or 80S20 machine, before a re

|Yes, I am aware of this machine being a Sanyo. I was told, however, that due to confidential agreements, Sanyo will not release any information pertaining to the specs of the machine. I was hoping to obtain the specs of the cutting blade to make my

The main criteria is at what frequency is the RF operating? If it's in the microwave region, forget no-clean. Low frequencies - 0 to 100 MHz, probably ok. Beyond that, it's application specific. Depends on components used and circuit design. The p

Using a flux pen sounds like a good idea. Comments are: * I assume you�re talking aqueous flux. If not, some NC flux pens leave white residues. Nearly all of 15 samples suffered to varying degrees with white residues. * Use the same flux that you

Another equipment manufacturer is Smart Sonic. Most equipment manufacturers have their own chemistries, but they are also willing to use other cleaners. What we have done is to send boards that need to be cleaned to the equipment manufacturer. W

Hi, It's removed from the fridge, and the tube is loaded into the stencil printer, however it's winter here right now, so it's still quite cold. It's Australia, so when I say cold, that's relative, however the room can be about 10 dec C in the morni

Finer pitch: Wedge bonding can be designed and manufactured to very small dimensions, down to 50 mm pitch. Processing speed: Machine rotational movements make the overall speed of the wedge bonding process less than thermosonic ball bonding. Alumin

Hello, I am automating a process on our floor from wire solder hand application to dispensed paste and reflow. The process involves "lidding" a shielding lid around our assemblies for microwave quieting. The result is non-hermetic. For cosmet

I am currently contemplating the purchase of a pcb prototyping machine. The machine will be used to prototype some patch antennas, microwave circuits, embedded systems, boards for various surface mount chips evaluations, possibly milling PZT materia
