Why don't you look in the datasheet?
Normally the plastic foot has two cut corners = plus some sort of stripe at the can = negative Let me also point out that SMD parts are made for machine soldering.

Speaking of drilling holes unless it's for cell phones... I just read an article in a trade magazine discussing relative merits of bonding wire to terminals on the ICs that are stacked FOUR and FIVE tall inside cell phones
![]() anyhow- On some of our PCBs here at work, the surface mount caps have a stripe on one side that is oriented toward a "+" printed on the PCB. HTH

hello,

![]() It's useless to tear them apart.... I have checked out the structure diagram. The anode is almost symmetric to its cathode. really! ![]() ![]() Also, I don't think it gonna blow up if you reverse the positive and it negative. At most, the wrong positioning shorten the cpas life. That's it. CC ![]() |

OK!!
The marked side is the cathode! This is the final conclusion after reviewing several SMD caps manufaturer's website. C.C. |

You can also solder SMD parts per hand - 0,2mm pitch is possible - although i got an hurting red eye after 500 pins ![]() Greetings Ralphono |

I also use the hot air soldering equipment. comes useful for shrink tubing too.
![]() I only use hot air for resistors, IC's, transistors, ceramic caps. I always think electros and tants hate high temps. |
