... FOR YOU AS THE USER? Not only is the chemical silver refinement uncomplicated and reliable, but once the manufacturing parameters have been set they | CIRCUIT BOARDS FABRICATORS | can be dependably utilised for further processing and continued use. Due to the thin surface layer – a thickness of 0.15 – 0.3 mµ is | CIRCUIT BOARDS FABRICATORS | recommended – the surface of the pad is smoother and therefore there are, even in fine pitch areas, no restrictions when assembling. The silver functions | CIRCUIT BOARDS FABRICATORS | merely as a protection against oxidation, and the actual solder point is between the copper and chemical tin, therefore the solder point is absolutely stable. | CIRCUIT BOARDS FABRICATORS | It fulfills all UL requirements (UL796 specif.) and meets the usual requirements of automobile manufacturers: Test results Test AlphaSTAR Result Requirement SIR 85°C/85%RH 2.46+9 24h | CIRCUIT BOARDS FABRICATORS | Passed >1E+8; IPC- 4553 IPC-TM-650 2.6.3.5 3.15E+9 96h Passed SIR 35°C/85%RH 100VDC 3.56E+11 24h Passed >1E+10; IPC-4553 and GR 78 (Bellcore) IPC-TM-650 2.6.3.5 4.62E+11 96h | CIRCUIT BOARDS FABRICATORS | passed EM 10V bias, 100V Test 2.46E+9 24h ...

... baffle system effectively removes the solvent from the liquid solder mask without starting the cross-linking action. Screened panels are manually loaded into the conveyorized | CIRCUIT BOARDS FABRICATORS | oven as they come off the screen printer. The dried panels are automatically loaded on to an accumulator for cool down and availability to the | CIRCUIT BOARDS FABRICATORS | imaging operation. Image LPI Mask Dried solder mask is imaged in a manner similar to that used for imaging the circuitry. Phototools containing black areas | CIRCUIT BOARDS FABRICATORS | where the solder mask is to be removed are placed in direct contact with both sides of the panel. The panel is then exposed to | CIRCUIT BOARDS FABRICATORS | UV light. The amount of light used is controlled by an integrator. Printing is done with a semi-automatic dual drawer printer. While one drawer is | CIRCUIT BOARDS FABRICATORS | being loaded with a panel and phototools, the other is inside the machine being exposed. This dual drawer printing system runs at the same rate | CIRCUIT BOARDS FABRICATORS | as the screen printer to insure continuous flow. Develop LPI Mask After the panel has been ...

... specs, the fabricator might have to modify the data, and that's the last thing you want. So now we have an alternate reality: You've | CIRCUIT BOARDS FABRICATORS | finished the PCB layout (check out those negative planes!). You output the 274X and IPC-D-356 netlist files. The data are fed into a fab analysis | CIRCUIT BOARDS FABRICATORS | tool and run through their paces. Clearances are good. No possible soldermask flaking. Spacing between the drills is just right. You hand the data set | CIRCUIT BOARDS FABRICATORS | to the fabricator, and voila! No unexpected phone calls, no changes in the layout, and the fabricator happily sends back a good set of boards | CIRCUIT BOARDS FABRICATORS | on time. Our recommendations for the correct storage of PCBs and MLBs A.1 ) Brief desricption of the problem: PCB`s, especially Multilayer boards are extremly | CIRCUIT BOARDS FABRICATORS | sensitive towards moisture The microscopic structure of the Multilayer material develops a strong capillary power that soaks up the humidity of the surrounding air. Even | CIRCUIT BOARDS FABRICATORS | under very dry conditions it is a question of time that water accumulates in the stored ...
