... essential if inner layers need to be tested, as is the case with multi-layers. In two position measure-ments all connections in the PCB are | PRINTED CIRCUIT BOARDS MANUFACTURERS | checked for stoppages and short circuits. All SMD pads and plated through holes are checked. The electrical test can be conducted as a parallel or | PRINTED CIRCUIT BOARDS MANUFACTURERS | finger test. Parallel test: For the parallel test a control adaptor is constructed, consisting, e.g. of several synthetic sheets positioned above each other and fitted | PRINTED CIRCUIT BOARDS MANUFACTURERS | with control pins. An adaptor programme must be written to reflect the actual holes in each individual synthetic layer of the adaptor. The pin positions | PRINTED CIRCUIT BOARDS MANUFACTURERS | are identical to the control points enabling an overall PCB test within seconds. The control adaptors are all the more expensive the higher the density | PRINTED CIRCUIT BOARDS MANUFACTURERS | and the lower the grid distances between control points. The adaptors can also only be used for one specific type of PCB which explains the | PRINTED CIRCUIT BOARDS MANUFACTURERS | high set-up costs for the test. Finger Test: As PCB series are not always produced in mass, ...

... Panel Plating a Flash of Copper The panels are online in a wet state transferred to our automatic electrolytic copper plating lines to get | PRINTED CIRCUIT BOARDS MANUFACTURERS | a flasch of copper.. The panels are attached to plating racks. When the racks are moved to the loading station, the system computer instructs the | PRINTED CIRCUIT BOARDS MANUFACTURERS | hoist to pick up the rack and begin the plating cycle. The copper plating time is approximately one hour. Electrolytic copper of minimum thickness 12 | PRINTED CIRCUIT BOARDS MANUFACTURERS | microns is deposited on the surface of the panel and on the walls of the drilled holes. This is achieved by applying an electric current | PRINTED CIRCUIT BOARDS MANUFACTURERS | to a cell comprising the panel (the cathode) and a set of copper bars (the anodes) suspended in a conducting medium (the electrolyte). A plating | PRINTED CIRCUIT BOARDS MANUFACTURERS | history log is maintained on the shop floor control computer which assists the operator in making minor adjustments to the plating current. Finally, the panels | PRINTED CIRCUIT BOARDS MANUFACTURERS | are rinsed and returned to the unload station. Sample measurements are made from each rack of panels to confirm the ...
