resistor networks- leadless vs. gull wing

Electronics Forum | Fri Sep 24 11:38:32 EDT 1999 | danielm

I am in the process of picking a new resistor network for one of our new board. Since we are new to SMT i would like to get some opinions on networks. Currently we use one molded gullwing type network on our boards with no problems. Other than space

| I am using a 18 mil and below water soluble solder paste (89.5-25-80). I have never used this type of paste. The PCB has a fine pitch component of which I cannot prevent bridging. The paste coverage on the pad looks like it is slumping. It is not a

I am looking for a rule of thumb regarding the maximum ramp standard components (chip capacitors) can tolerate without failure during the reflow process. The standard seems to be 3C\second, but this figure is generally derived from the average ramp
