No, none of us can tell you what is the acceptable level of halide content or contamination in flux residue. The level of harmful residues on your product helps determine the reliability of your product. We know nothing of your product, its custome

Hi there There are a number of things worth considering when viewing bga's. Firstly, like any other solder joint that you have been inspecting for years, suface finish is critical. Secondly, and again like other joints shape is important. Now it may

From time to time, component suppliers decide to discontinue production of components that we use in our products. Occasionally, these components can be sourced elsewhere or designs adapted or altered to accommodate alternates. In many cases, however

Hello Amol, I continue to be amazed at the surprise engineers have on discovering that a non-eutectic alloy such as SAC305 displays micro-cracking and rough joints in a soldering process. There was a reason the electronics industry chose to use eutec

Most of the "Economic Benefits" is a bunch of hand waving, but the one forceful point is: "Four companies of our survey mentioned monetary gains. One company states that it produces the same product for the world market as a result of RoHS. Due to ea
