Three popular methods: Resistivity of Solvent Extract (ROSE) Test Method IPC-TM-650 2.3.25: The ROSE test method is used as a process control tool to detect the presence of bulk ionics. The IPC upper limit is set at 10.0 *g/NaCl/in2. This test is p

I agree with Ken, the root cause could very well be obvious. However, take a look at the following items, these checks only take a minute to accomplish. 1. If your stepper drivers are the older 5410 Pac Sci modules, check for melted power connectors

Am I missing something here? I usually put some type of stiffener or support on the leading edge to make sure the PWB doesn't sag in the middle from the preheat. If I had to add a bean bag with shotgun pellets or BB's I would have boards falling out

This problem is not unique to China. Second user customers are always challenged to assess machine condition, upgradeability, service history etc. More often then not, candidate machines are located halfway around the world. Further complicating thi

Hi Mike, I haven't tried the 0201s with a Hyrda, but after seeing 20 reviews of your message without a response, I'll try and share my experience with 0402s on a non-Hydra machine. The 0402s are slow, but I managed to get some speed by maxing out

A good board used soon after you receive it should not delam. If only a small percentage is doing that I urge you to do some more looking at the board quality while you do the baking. Do a search of the archives on baking boards, Dave F had some good

I have seen 100% Matte Tin plating and a lot of Sn/Ag/Cu plating for gull wing parts. This is the most common type of plating. Also in a lead free process you will see that the very end Toe of the part will not flow. This is due to the metal being cu

Of course there are solvents which are less harmful to the environment than others. The operative phrase is �less harmful�. As a rule, water-based chemistries are �greener� than solvents. There are some solvent blends designed for aqueous-based eq

Armakleen is compatible with CPVC as are most aqueous-based chemistries. Armakleen, in its day was a superior chemistry. It was the first of the aqueous blends to offer bright solder joints (earlier saponifiers commonly dulled solder joints). Arma

Hi JEM, We just made the very same upgrade you are looking to make on three machines. We purchased a new MY12 and upgraded our other three (My9 W/hydra, My9 No Hydra, and TP9-2U) from 2.2.4C to 2.4.4c. There are several changes and most of the
