Ive used a Mirtec machine for 3 years MV3L with side angle inspection. Mirtec has some issues documentation, and repair plus. But there machine is impressive and the AOI software is good. We can find about 90-99.99% of all errors using just the 5

Steve, TI does not produce any SOTs using Palladium finish leadframes. I would certainly be interested to know who is. Also, your observations are correct: In TI experience the mechanical strength of the solder joints with Pd finish ICs is alw

soldering and bonding on gold PCB's

Don't sound proper. There is no specification. Pad peel strength test methods are: * IPC-TM-650, Method 2.4.21 for multiple solderings * IPC-TM-650, Method 2.4.8 for copper peel with a Instron machine. Typical requirement for Cu is: 6 lbf/in [1

I do recommend dedicated tips and dedicated workstations. Make sure that your tips come in with no lead in the tinning. There is a new, green heat resistant table mat that is being used in the industry to identify lead free areas. If operators see gr
