we have just started wave soldering passive SMT components and through hole. We are having trouble with voids on the SMT components. It is very random, but effects a lot of TSOT's. We are using an electrovert with a chip wave. Are there any obvio

| I am designing a component for surface mount. Does anybody out there specialize in the design of passive components for SMT? Can you recommend a good reference? | Raffi - Many companies have their own specs for parts, but I suggest you check

We are searching for an integrated passive component (or device) consisting of a resistor in series with a capacitor in an 0805 package. Cap value is .01uF, resistor value up to 1 meg. Any suggested sources appreciated. Miked@emcohighvoltage.co

Hi Folks, This is my first surface mount board, so I asked our assembly house for some tips. They said only passives on the bottom side-preferably no smaller than 0805, 0603 only if I have to. I would think that an SOT-23 would be OK on the bottom.

I was told today that upside-down placments may not cause thermal problems (at least according to one of our suppliers). Sounds like this problem could be application-dependent (supplier, R-value, actual wattage). Does anybody have hard evidence th

What is the level of interest in bulk feeding cpassive devices, caps & resistors, 0402,0603,0805? The component mfgs. tell me in 3 years 40% of the passive caps will be bulk fed. Their is currently about a 10% cost savings with bulk over tape & ree

We have problems of solder shorts while using DEK Infinity printers. Some of the manufacturing lines are configured ina way that the side (bottomside) of PCBs mostly with passive parts is screened first and then the otherside (topside) of the PCBs w

I am currently exploring the option of screenprinting chipbonder for backside devices, mostly passives, 0603 and up. Does anyone have any experience with this? What are the pros/cons? What are the stencil design considerations? What about blades,

Is there any difference in performance when running paper tape or plastic? What's the smallest passive component that you have fed in the feeder? How does pressure sensitive adhesive (PSA) tape perform in the feeder? PSA has a tendency to transfer

Not to be off-topic, but push engineering for embedded passives and remove parts from the underside all together. Watch the material cost sky rocket, but watch the manufacturing cost sink and well as improve the production cycle by 50%. Sorry, I w
