Jorge: Nosotros tenemos una óptica 0KM embalada perteneciente a Martín. Se la dio a Bruno cuando palmó la nuestra, sin embargo el equipo nuestro tiene el otro modelo. Si querés pasala a buscar y la probás. Estoy seguro que es la solución al problema,

What is a typical SMT placement defect rate?

Electronics Forum | Sun Sep 21 15:48:48 EDT 2014 | gascon5383

Our company has a process standard that requires a double person check at the beginning of every run (size of run is irrelevent, whether 20 panels or 500 panels). Every changeover that occurs a first piece inspection is made before reflow. If all is

High Melting Point Solder with alloy composition of 93.5 Pb 5 Sn 1.5 Ag

Electronics Forum | Mon Aug 25 08:15:54 EDT 2014 | jax

With a melting point of roughly 300°C, you would need to have the product see temperatures peaking around 325°C at a minimum. (I would make sure the components and PCB materials can withstand these temperatures) Most convection ovens do not go over 3

We have the possibility to buy a used Zevatech FS710 pick&place machine with vision. I've read that these machines used to be very well built but I'm wondering if it's capable to place 0603 parts accurately since it lacks a laser-type alignment AFAIK

I chose a Vitronics XPM3i primarily for the AutoSet automatic profile generation feature. We are high mix and simply cannot profile every board. The AutoSet feature is quick, easy and we rely on it 100% and have great results. These ovens have had ve
