Do you have any input as to the vibrations seen on the end-use device? Types of device(s) that have solder joint failure? How many thermal cycles the PCB goes through before failure? There are several areas in production of the board that could be th

Bruce Barton: We're not intending to suggest that anyone is purposely leaving WS flux residue on the board after cleaning. Fact is, Arun isn't sure if the boards are completely clean. Arun said, "We haven't tested the substrate for cleanliness." Gi

I am looking to scan small 2D barcodes in-line while the circuit board is on a conveyor. Currently an operator is picking board up off the conveyor to scan them. We want something that is fixed and does not need to much manual alignment from changeo

The low solids flux that is commonly called no-clean can affect some circuits. We are building a PCB that measures pico amps. The customer required that it be cleaned. We would rather used the low solids and eliminate a step. The customer had

While it's possible, we don't think that soldering a wire of this low of an AWG to a board is a good idea. We're concerned that mechanical vibration and heating / cooling will stress the solder connection to the point of failure during routine table

I'm new at this and any help will be appreciated. I received cad data from a customer and need to get it loaded into a Topaz system. The data is for a single board but the production board is panelized and has edge rails. This means that the actual

We are using a right-angle SMT power connector on a board. The connector has 4 leads and two board alignment pins. The layout for the board is such that 1 of the leads is not used and the pad for the lead is not connected to anything, not even grou
