Dendrite growth is not typically associated with a flux reation but rather is a result of mechanical stress. The stress can be from any source including stress induced by other components, environment, plating or even bimetallics. Dendrites are most

| | We're getting field failures in a high impedance portion of the circuit. Think the unpopulated pc card has contaminates because we were able to grow dendrites by applying a 9 volt battery across the suspected pad, placed a drop of de-ionized wat

Tony, Conformal coating will protect the board from outside moisture but will also encapsulate Ionics and moisture when present on the board.

Hi All, Thanks for your inputs...I really appreciate it!! Rgds, Sean

any evidence of dendritic growth?? (cause of the presence of condensed water due to high humidity level)

You're right on both accounts. Thanks for straightening things out.

i am working on a no-clean process implementation project in a company. i want to change a board to no-clean which had dendrite problems underneath the small resistors on the bottom side(in smt).i want more information on the exact cause of dendrites

Hi guys, i do not have a lot experience on this wave solder process, in my plant now i have the opportunity to work in this area, and a lot issues are been happening on the process and it could be possible that i request information about this, i hop

From your description of the problem first reduced SIR to dead short is exactly what happens with dendrite growth. What is needed to form them is low bias voltage (10 volt range is ideal with low current), a surface, 2 conductors (containing tin), io

Dendritic growth is always a result of three combined factors: Conductive/corrosive residues Electrical current Moisture A wave solder process normally applies a higher volume of flux than a printed process. Flux however is not the only source. F
