 //i have had a few peeling pads when doing these boards, it seems that the recoil from the pump hitting the hot pad/trace can strip it off sometimes... (it's certainly also bent some very thick wires) i'm going to get some desoldering braid instead//

+===== Some More Tips =====
   * Make sure your board is //clean!//  A bare copper board has noticable oxidization within minutes.  Before soldering, consider lightly scrubbing your board with steel wool and a little solvent (isopropyl alcohol works well).  Even tinned/plated boards are filthy - you'd be surprised what you wipe off if you pour a little alcohol on it and rub it vigorously with a paper towel.
   * Only use rosin, or rosin-mildly-activated (RMA) flux-cored solder.  Do not use solid solder wire, and especially don't use plumbers' "acid core" solder!  Flux is an often neglected, but essential ingredient for a good solder joint.  When it heats up, flux cleans the surfaces so that they can better bond with the solder.  RMA flux is best because it does not remain corrosive after it cools off.
-  * It is good to have some extra RMA flux on-hand for when you need to reheat a solder joint.  Common flux dispensers look like squeeze bottles or liquid paper bottles.\\

   * [[http://www.nuxx.net/wiki/Flux_Removal | Flux Removal]] - A convenient way to remove flux from a PCB after soldering. Requires no special chemicals or tools. --- //unknown 2006/08/03 //
   * What Smash said above notwithstanding, if you //really// want your wick to work well, wet it with some flux first!
-  * The best tip for your soldering iron is not necessarily the smallest.  In fact, you want the tip that will allow you to best heat up the surfaces to be soldered, by making the best contact.  Such a tip should have a flat edge to make the best contact with a round component lead.
+  * The best tip for your soldering iron is not necessarily the smallest.  In fact, you want the tip that will allow you to best heat up the surfaces to be soldered, by making the best contact.  Such a tip should have a flat edge to make the best contact with the pad (or component lead).
   * On boards with plated thru-holes, lay the flat edge down on the pad with the side of the tip touching the component lead.  Hold it there for about a second prior to introducing solder.  This ensures that the entire plated thru-hole heats up enough to melt (and subsequently bond with) solder.
-  * On boards without plated thru-holes, the component lead is harder to heat than the pad, so hold the flat edge against the lead and the end against the pad.  Add solder after about a second.
+  * On boards without plated thru-holes, the component lead is generally harder to heat than the pad, so hold the flat edge against the lead and the end against the pad.  Add solder after about a second.
   * Do not put a gob of solder on your iron then just wipe it on the joint to be soldered.  This rarely works well.
   * After you remove your soldering iron from the joint where the solder is melted, it takes a second or two to solidify.  This period is referred to as the solder's "plastic state".  During this time period it is essential that you do not disturb the joint.  In other words, never allow the board to be jarred or shaken immediately after you remove your iron, and do not allow the component lead to wiggle.  The reliability of the joint will be compromised if you do.
   * "Standard" electronic solder is 60% tin and 40% lead.  The best solder is 63% tin and 37% lead.  This combination yields the shortest "plastic state" - put simply, it solidifies faster after you remove the iron.
-  * Flux residue after soldering is common.  It's a good idea to clean this, because certain fluxes (not RMA however) remain somewhat corrosive.  All fluxes remain a bit sticky, and subsequently attract dust.  You can clean flux off with isopropyl alcohol, or any of a wide variety of spray-on flux removers.

   * After handling solder, do not eat, smoke touch anything which will enter your mouth without washing your hands thoroughly with soap and water.  Solder contains **lead,** a heavy metal which never really leaves your body - it can't be good!
-Hopefully these tips will come in handy.  My work sent me on a 6-day soldering course covering thru-hole and surface mount rework and repair a few years ago, and I found it incredibly handy!  Happy soldering! -nebula

+==== And Even More Tips ====
+Black Light - The best and easiest way I've found for checking if there are any bad solders or shorts on my boards is to look at the boards under a black light (I'm using a screw in fluorescent bulb). The resin board comes out bright green and the solder, which I find a pain to see clearly sometimes, comes out dark purple. You can easily see any missed pins or anything else that may cause problems later on. -MOG151;)
