Hello,
Thanks, do you think the attached is better? There is now a single copper pour connecting all LED Tabs. The isolation between this pour and other copper is 0.3mm. I hope this is OK for MCPCB? (the distance between the LED pads is in fact less than 0.3mm and is unavoidable) I presume that there will be no problems with heat being 'wicked' away by this extra thermal conenction to the LED TABS. As you say, the whole thing will be heated up ready for soldering, so heat getting 'wicked away isnt so much of a prolem for MCPCB boards?
All topcopper is 70um.
