Supply throughout the sensitive type etching resist ink corrosion ink

Guangzhou City Friends of Development of New Materials Co., Ltd. (Friends of ink) Tel: 15323364649 QQ512330637 Miss Lai YB-8320 & 8330 liquid photosensitive anti-plating and etching resist operating parameters and precautions operational parameters 1, the front substrate outside the grounds chemically or physically CCL on decontamination, and roughening its surface, a rear surface processing board before coating should be neutral, in order to ensure good adhesion and coating uniformity. 2. Stir before opening oil use 3-5min, when necessary, special open water may be added to adjust the viscosity, proportional control of 1% or less, if you need to use open water must be checked topcoat film thickness uniformity of the board, and if there is dew copper and other issues. 3, printing 3.1 mesh: ink printing mesh using 77-100T, white screen printing; 3.2 scraper: A 75 3.3 Printing Notes A, printing plate when the left and right sides alternately shift, preventing the ink into the hole; B , screen room must be kept clean, mud layer (dirt) and so will adversely line coating and distress; C, must work under the yellow light when printing; this product is not suitable for under white light or daylight operation; D, in addition to add or stirring ink, please feel free to cover the tank to prevent solvent evaporation caused by increased viscosity of the ink; E, normally without dilution, if the subject to adjust the viscosity, please use our special diluted class agent; F, when the ink is less than the thickness of the coating thickness, It will produce plating overflow suspended (OVER-HANG) phenomenon leads to the completion of the short circuit and plating ink difficult or unclean, unclean cause etching, in order to avoid this situation occurs, as the anti-plating ink film thickness than the coating thickness to be beneficial produce. 4, the pre-bake 4.1 Printing After standing 10-20min; 4.2 pre-bake temperature of 75 ± 5 ℃; 4.3 hours: the first face: 8-15min, the second face: 15-20min; both sides with baking: 20-30min; Remarks : The above parameters for the production oven, tunnel oven if it is required to adjust the temperature and time according to the machine performance. 5, the choice of power 5KW exposure 5.1 or better 7KW cooled workers exposure; 5.2 exposure amount 120-150mj / C㎡, 21-foot wedge control in 7-9 plastic film; 5.3 Exposure vacuum degree requirements more than 95% ; 5.4 countertops temperature controlled at about 18 ℃. 6, developing a concentration of 6.1 developer: Sodium carbonate 1.0 ± 0.1%; developer temperature: 28-32 ℃; 6.2 spraying pressure: 2.0kg / C㎡ above; 6.3 development time: 40-60s; 7, after drying 7.1 gilded board and resist plate without baking; 7.2 tinplate and 3 / 30z copper etching plate above; recommended 120 ± 5 ℃, bake 10-20min help anti-plating 8, Stripping 8.1 have post-baking The plate; soaking temperature of 50-55 ℃ 2-3min solution;; 5% NAOH 8.2 without post-baking of the plate: 5% of NAOH; solution temperature of 50-55 ℃ soak 1-2min; Note: 1, this product is stored in a clean environment and temperature 10-25, relative humidity 50-75% RH, storage and handling sites, allowed to be operated or stored under white light or sunlight. 2, this product is recommended to use oil, such as when you need to adjust the viscosity, use this product thinner (do not use 783 open water), proportional control within 2%, Stir before using 3-5min. 3, the surface of the substrate treatment have a critical impact on the wet film, in order to ink on a copper foil has superior adhesion, clean respond board and no oxide layer and dried for testing to confirm the degree of side etching and then adjust, Exposure control at 7-9 foot plastic film. 4, ink thickness required for different exposure energy is different, pre-production testing please confirm the extent of side etching and then adjust exposure control in 7-9 foot plastic film. 5, within 48 hours after printing required exposure and development. If the operator places the case of large deviations of temperature and humidity, to be completed within 12 hours. 6, developer concentration and temperature, pressure and nozzle cleaning, time must be standardized management, such mismanagement could easily lead to the development of low ink, the side effects of erosion and flushing. 7. In case of contact with skin or eyes immediately with soap and plenty of water, do not use any solvents. 8, the product is combustible, storage and use of premises is prohibited fireworks.
