If you have concerns, you can look at the datasheet for each component or contact one of their application or materials engineers and find out what the components are rated for...process-wise. IE, how long can I be in the oven with this part, at what

| I was wondering if anybody could tell what web sit rates the equipment in regards to speed? I was there before but forget the address. Thanks, | Check this website out, it has a few comparisons in the Equipment survey section. Cheers, Scott

Time and temp in lead and lead-free reflow

Electronics Forum | Fri Aug 01 21:10:35 EDT 2008 | leo_dektec

You can keep only the 5th zone as the reflow zone. And lower the first two zones to keep a good ramping rate. Meanwhile,please note the ting temperature in software or control panel is not the exact temperature in your PCB, you'd better get a KIC or

Time and temp in lead and lead-free reflow

Is there a limit to the time that most components can stay at temperatures around 130-200 deg c? if i slow the time, the first 4 zones will be at this temp for about 5 minutes in no lead process. i am concerned that some chips wont be rated at this t

Universal GSM and 0402/0201 Placement

We did 0402s for years on a GSM. Is this a flexjet or a 4 spindle head? A flexjet is easy with 0402s. The four spindle nozzles are big, you run into issues with knocking already places parts and having to Z zone carefully (and beware repair cycles.)

Hi Mike, I haven't tried the 0201s with a Hyrda, but after seeing 20 reviews of your message without a response, I'll try and share my experience with 0402s on a non-Hydra machine. The 0402s are slow, but I managed to get some speed by maxing out

I appreciate your comments regarding the programmability of the Mirtec. What type of SMT machine do you use? How easy have you found it to transfer the SMT profiles to the Mirtec? How do you rate the Mirtec in handling top/bottom, multi-panel asse
