| | If passive componets are cheaper why aren't they more popular? Manufacturers like Murata and AVX claim availability and substantial cost savings but little interest seems to exist. Why? Your input is greatly appreciated. | | | Because people ju

Hi everyone, I'm relatively new to SMT PCB design and am running into some frustration with the land pattern design of "standard" smt components in particular passive chip components. It seems each manufacturer (Yageo, Rohm, Panasonic) has their own

Hello, I havea 0.4mm pitch TQFP with heat transfer pad on the bottom side of component. I will appreciate any suggestions with regards to: 1) stencil thickness (Rest of components on board are 0603 passives and few 40 mil pitch IC's) 2) Stencil

Current Acceptable HMP Soldering Methods: 1. Wave / Selective Solder: Some Brands require upgrades to heating elements and Pot materials 2. Laser: Works well with PTH and medium/large passive SMT. Damage to PCB masking can occur when try

We're not sure what you mean by temperature sensitive components. From an assembly process stand-point, every component we use is temperature sensitive to one level or another. More specifically, some of our products use polyphenylene sulfide (PPS)

Hi, It seems weird that an automated pick and place machine at a board shop would not be up to NASA standards, but placing the components by hand would be. However most SMT will self center a bit, so if your close enough, you should be ok. You rea

Maybe it is all what you get use to. Our assemblers like the vacuum pen. Since we do more than passive components, some parts would be difficult to hold and line up. As for as our Fristch, we use it as a manual and just have our bins on the side.

Hi, We used to use large reels of 0603 passives, but now we have moved to 0402 our supplier only has standard small reels. That's actually less components and we have to change the machine more often. Anyone know any supplier that has the very larg
