Hi, It's both really, and we are doing higher volume of current products, but new products are increasing in component count, mostly passives. We have analog on our products, and this uses a lot of passives, plus each semiconductor needs decoupling

We use Samsung here and we have beat the $#^ out of them for 5 years straight with no machine failures to date. Granted it's not twenty years but we will see. What are the majority of these passives you are placing in relation to size? Not a Samsun

Hi Grant, What sort of volume of 0402 resistors are you using - I may know someone who would put them on the larger reels.

I'm new on this, what's the standard rate for each placement on passive and active components and how to rate labor cost per hour. thanks in advance

No Chunks, I did not tell him to "stick it", yet. I've decided on a new way of handling this IDIOT. I'm gonna try some passive-aggressive techniques. You know. Sarcasm and manipulation? Will see how that works.

You can adjust to 45mm clearance, But I would recommend staying at 25mm if working with fine pitch and smaller passive components.

Hi, most common parts were mentioned already. For all the rest you will have the simple counting we all do. Distanse between two holes in the tape is 4mm. You dont need special software for that. packages for passive parts you will learn fast.

We're sorry not to have replied sooner, but we just lost track of this thread. The chart is from a course taught by Martin Tarr at the University of Bolton.

I would run the passive side first just because the BGA is probably moisture sensitive and I wouldn't want to have to keep track of the time between first and second reflow.

On any new project we use double sided tape and place all the components to check for placement accuracy and polarity prior to pasting a board. We salvage any large/high dollar parts and toss the passives.
