Before you start to hand solder a quad flat pack (QFP) to a printed circuit board, you will need several tools and items. This article describes what is needed for the process, including safety items, consumables (materials that are “used up” during the process) and tools.
Still on the subject of air safety it is important to make sure that your work area is reasonably well ventilated so that there is Face mask not a build up of solder fumes where you are working.
Prime the ceiling. Start on the short side of the room and “cut in” the edges about 2 inches wide and about 5 feet long along the edge of the ceiling. Then, wearing safety goggles and an old cap , roll paint onto the ceiling, working the roller into the cut-in areas to remove as many brush marks as possible. Roll with diagonal strokes and move from the edge toward the middle of the room. Continue cutting in and rolling until your are finished.
Cut in a section of the wall. Wait until the ceiling dries and mask it off with blue painter’s masking tape. Mask off the trim if you haven’t already done so. Starting in a corner, prime along about 5 feet of trim, 5 feet of ceiling, and from top to bottom of the corner.
One surefire way to rid your home of molds is to hire the services of a professional. Mold removal experts like an indoor quality professional are also willing to do mold remediation plans where they indicate what exactly needs to be done in your home. Of course, you can pay them to do everything themselves. They can do all the tasks necessary; from inspection or assessment, to making restoration plans, to mold removal, basement waterproofing, foundation repair, and everything else.
And you’ll need stencils – hence the spray paint stencils part! The variety of stencils available to you is mind numbing. So, it’s next to impossible for me to recommend any one kind of stencil because I don’t know anything about your project. My best advice is to experiment and test different stencils and materials.
Then very carefully touch the solder blob onto one of the corner pads. It doesn’t matter if you get 2 or 3 pads at this stage. Don’t let the actual soldering iron tip touch the legs – you just want some contact of the molten solder to the leg and the pad.
Carpets, upholstery and other porous items are harder to clean. You will need to clean them, disinfect them, and then wait for them to totally dry. If you see any re-growth of mold, you will either have to throw that item away or get a mold removal professional.
