I guess, we may add a silkscreen “+” i “-” just outside of the footprint on either end. Just put the diode schematic symbol on the silkscreen. Very Clear.

I recently purchased LEDs on ebay that were supposed to come attached to star PCB (as a heat sink). The items I received are just the LEDs (no PCB). They are listed as 3W LEDs, with a forward voltage of 3.0-3.4V, and current at 700mA.Will I damage/destroy the LEDs if I use them without a heat sink? Jeśli nie, what is the best way to mount these to preserve their life during operation?
I believe I have heard of putting a plugged via right next to a mechanical pad so that the board is stronger there. But I’m not sure what the implications are for putting a via on the pad?
Wiem, że stosowanie procesu ołowiowego w bezołowiowych układach BGA jest niedopuszczalne, ponieważ kulki lutownicze BGA nie stopią się i złącze będzie zawodne. Ale teraz chip BGA jest dostępny tylko w kulkach bezołowiowych. czy można lutować ołowiowe chipy BGA bezołowiowe? (a zatem, podwyższona temperatura) proces?
