Preventive Repair: Resolder Questionable Solder JointsWhat initially appeared to have been the source of the “Pump Motor Runs When Unit is Off” problem seemed to have been the totally lousy solder joints on every joint on this particular circuit board....
highly desirable as in circuit board assembly processes up to 80,000 components may be used in each assembly line per minute. If a single component is defective, it is typically more cost effective to scrap the entire finished circuit board, rather than identify and repair any manufacturing ...
I soldered a short length of 1″ copper tube into it to form a transition from the chimney rim to the funnel. The disc was cut from copper clad circuit board (using hole saws with suitable clamping) to form a centering device for the transition piece. The scollops in the PVC coupler ...
The second production step is having all of the electronic components soldered onto the empty board. From your design software you’ll be able to output a file that shows the exact coordinates of every component placed on the board, which is commonly called apick-and-placefile. ...
