Lead free and product design

Ioan,

A lot of this will depend on the type of product you are manufacturing. If you are producing a product like a PDA, you will be able to get by with a 235-245 C peak temp. If you are building bigger boards with heat sinks, etc. you may have to go to 260C (good luck!). Being in the lucky group we are not going to have to change our boards at all. We are now squeezing the component suppliers to get components that can meet the temp profile requirements. You need to engage your designers NOW so they pick appropriate components for new designs so you don't have to go through the whole process again.

Ammo? If they don't help you and you don't get parts, you won't be able to sell into Europe. Period.

Hi Technos,

"our designs are perfect, lead-free is a manufacturing problem"... Does this sound familiar to you? Well, I got to hit this wall, me too.

Our product developpers don't really feel like they should hop into this train.

There are 2 things I would like to ask you:

what ammo (technical, of course) should I use to change their minds
besides deciding on a suitable alternative finish of the PCB, higher Tg FR4, picking the right components, is the intimate design of the PCBs affected by the Pb-free? I mean, different land patterns, clearances, via technologies, etc.? What about solder masks and marking inks?

Any clue would be largely appreciated.

Thanks,
Ioan
