Peter,
        Provided your oven is a convective reflow system, you should do well with this oven.  With that said, let me add that you will need to verify that your existing profiles will work as well with the BGAs you are processing.  This will require instrumenting boards with thermocouples and measuring their temperature responses.  If the components/boards you are using are just too expensive for this, I would suggest getting some dummy parts and board and use them.  Just be sure that the dummy components/boards accurately represents the board you are using in production.

Hope this helps,
John Guy

Subject:        [TN] New reflow oven needed for BGAs???

Hi all,

We are looking at placing BGAs. We currently use a 5 zone reflow oven that
does a great job of soldering all other components. In fact, we only have a
few profiles which are used on many products.

Is there a need for more zones when going to BGA? Does size BGA size matter?

Thanks in advance,

Peter
