Hello! Does any one know of a disadvantage of using the Phillips recommended wave solder SOIC footprint where the last pad on each side of the SOIC is enlarged, instead of placing an extra pair of pads behind the SOIC. Both footprint patterns seem e

Hi Dave! Dat' be da same board we ran at NEPCON East in 97'! Ray Rua was running the TAC line then (his company usually runs the TAC line at almost all NEPCON shows). A couple of things I wanted to point out on that GIF image that might b

Istv�n: Given a choice, I�d run second side PLCC44s at 90� to the wave. As far as thieves are concerned, I�d have two, mirror images of each other. Unlike most, these thieves are not connected to pads. They are out-side of the last pad on the sid

If I were you, I�d be concerned about waving your SO18 too. What is a SO18? Who makes that package? Regardless, it should be a can of corn, if you: * Orient it so that leads on opposite sides of the component see the wave at the same time. * Incre

| We are wave soldering a board having 24 similar thru hole connectors on it, using a wave soldering pallet. The problem is that one particular pin of connector in around 6-9 connectors get excess solder on the bottom side. I have tried all the par

When you say well designed for wave, does that include "extra" solder pads for the IC's for solder thieving? And Boards that are well designed for wave don't have QFP's on the bottom. They might be ok but then the board would be "ok for wave", but no

These parts are flat chip resistor arrays that have 4 end terminations on each side. It looks liek an IC but is typically in an 0805 and 1206 package type with convex terminations. .031" pitch from termination to termination and .011" spacing between

A lot of your success with waving SMT components is dependent upon design and what type of wave forms you use. Without knowing how the board is laid out or what type of wave you have it is pretty difficult to determine what the yield differences wil
