Pattern Plating In the pattern-plating method, after the copper reduction process, plating resist layers of the reverse conductor image are formed on both sides of the panel by screening resist inks In most fineline boards, photosensitive dry film is used instead There are some minor variations in the pattern-plating method (see Fig 56): 1 Catalyzing (preparing the nonconductive surface to cause copper to come out of solution onto that surface) 2 Thin electroless copper (000001 in) followed by primary copper electroplating; thick electroless copper (00001 in) 3 Imaging (application of a plating resist in the negative of the desired finished circuit) 4 Final electroplating copper 5 Solder plating (as etching resist) 00002 or 00006 in 6 Stripping plating resist 7 Etching of base copper 8 Solder etching (00002-in case); solder reflow (00006-in case) 9.

Solder mask followed by hot-air solder coater leveler if solder etching is used 10 Final fabrication and inspection Most manufacturers of DSBs with relatively wide conductors employ thick electroless copper plating However, thin electroless copper followed by primary electroplating is preferred for boards having fine-line conductors, because a considerable amount of surface is brushed off for better adhesion of dry film This provides a higher reliability for PTHs Solder reflow boards had been preferred by many customers, particularly in military and telecommunications applications, until the emergence of hot-air solder coater levelers Although the solder-over-copper conductors protect the copper from oxidization, solder reflow boards have some limitations Solder mask is hard to apply over reflowed solder, and it tends to wrinkle and peel off in some areas when the boards go through component soldering.

A more serious problem is the solder bridging that occurs when the conductor width and clearance become very small In step 9, the entire surface of the board except for the pads is covered by solder mask, and then the board is immersed into the hot-air solder coater leveler, resulting in a thin coating of.

The calculated value (033) is used in Figure 750 The intersection of L/D (15) and l/L (05) read on the vertical axis does not reach the C' value of 033 From Figure 748, the intersection between the L number of jets per row (20) and the curve gives a value of 12 on the vertical axis, which represents a 20% increase in load for increasing the number of jets The intersection of L/D (15) and l/L (025)

The liquid coatings can be applied by a variety of methods, including:

Hand painting the coating with a brush Dipping the board into the coating Hand spraying with an aerosol can or handheld spray gun Automatically spraying the board with coating as it passes by on a conveyor Selectively applying coating to certain areas of the board with a robotic nozzle Vapor depositing para-xylylene onto the board with specialized equipment

Hand Paint Hand painting allows coating to be applied wherever desired with no setup time and low equipment cost. It is still the preferred method for touching up thin spots in a bulk applied

coating and for coating replaced components. It can be used to reach areas where spray or automatic nozzles cannot reach, and works well for smaller, one-of-a-kind items. Hand painting is the most variable of all methods. 41.4.2 Dip Dip coating works best for coatings that have a long pot life at room temperature, such as solvent evaporation cured coatings and one part materials. Since the unused coating remains in the dip tank, a long (or infinite) pot life keeps the waste down to a minimum. The viscosity of the material in the bath should be checked daily, using a flow cup viscosimeter or other method, and solvent added to keep the viscosity of the material within the acceptable range. For a given dip speed, a lower viscosity will produce a thinner coating. The dip machine (see Fig. 41.2) will have bars or hangars on which to hang the board to be coated. Insertion speed should be slow enough to prevent the formation of bubbles as the coating flows around and under surface mounted parts, etc.Withdrawal speed should range between 1 to 6 in./min and will dictate the finished coating thickness; a slower withdrawal will produce a thinner coating.
