Sorry, I am jumping into this late - I'm a new user. Our company is looking to perform an evaluation for a new paste. We are looking at a 63/37 no clean - type 3 or 4. Our technology is currently at 0201s, .4mm pitch ICs & .5mm uBGAs. I have

Flashback time� Vapor degreasers, although still used in limited applications, no longer represent the conventional wisdom (due to multiple environmental issues). Aqueous-based technologies are the most common method of defluxing. Unlike most va

About SACX307 for wave you can read at post: http://www.smtnet.com/Forums/Index.cfm?CFApp=1&Message_ID=38727 As I have heard, in Europe, Germany in particular, several assemblers are using SN100C for wave (also HASL) with success since years ago.

We tested SAC305 in our selective solder machine and found the dross production made it an unnaceptable choice of alloy. Personaly, I cant imagine dross in a joint being a good thing but if it is a very small amount and does not occur very often, y

Opinions. I have a large finned heatsink that we place over a D2pak transistor. This heatsink is designed to heatsink the transistor through the junction of the pad area that the transistor is attached to. The paste pattern we chose was small dots ar

I would agree with JAX for a general estimate. If you have a few specific boards Universal can put them in a simulator and give you pretty close estimates. I would reccomend you go to thier NY facility and actually run some boards and get to know the
