| We currently use an ESP RMA paste. The reason that I initially posted the question was because we are conducting tests to see if this is infact the best paste for our processes. In running tests, however, certain variables, such as humidity, are

| We are having some difficulty soldering a 240 pin Altera device. We use Alpha WS-609, a very generic profile for that solder paste, and a 6 mil stencil with laser cut apertures (1:1 ratio). This is a 20 mil pitch device (aperture size is 10 mils X

I am an equip mfrs rep. I took a customer to my wave solder principal's factory to run their boards on a wave with no-Pb alloy, (Sn96.5 Ag3.0 Cu0.5) in air environment. The results were excellent with pot temp of 263C (505F). Their boards are low to

I like AIM solder paste, personally. But, much like asking which pick and place machine is best on this board, you're likely to get as many opinions as there are paste manufacturers. I just took a look at Alpha's datasheet for this product, and it

The ISL12020 real time clock comes in a 20 lead DFN, and includes a 32kHz crystal in the package. The terminals of the crystal and oscillator come out to external pads and are highly susceptible to leakage to the neighboring power supply pins. With

Hi Guys, So I work for a small contract manufacturer which caters mainly to the defense sector. As such, our customers haven't (yet) had a great need to incorporate 01005's into their designs. Looking forward, we decided to "take the plunge" and dia
