YOUGUANGINK CO., LTD Friends of Ink Co., YB-800 Series Liquid photoimageable solder mask technical information I. Introduction YB-800 series is a two-component liquid photoimageable solder mask, in 3mil green oil bridge control, BGA level plug hole high temperature lead-free HASL, resistance and gold, tin resistance, etc. all have excellent performance. YB-800 products are common type of environmentally friendly halogen-free. One common type of liquid solder mask has been compliance with the EU RoHS directive and halogen-free solder resist ink is in line with the requirements of high-end customers environmentally friendly products. Second, the operating process 1, the substrate surface treatment acid treatment and mechanical grinding brush 2, open oil the main agent and curing agent 3: 1 mixture, add the appropriate amount of diluent, stirring or shock for 5-10 minutes, so that the main solid mix evenly. 3, stand 10-20 minutes to fully discharge the ink bubbles generated when opening the oil, the ink viscosity stability. 4, the printing of the first side of the printed solder surface, a second surface side of the printed parts; ordinary plate 43T mesh, lead-free HASL, and gold plate or tin plate 36T net. 5, stand for 10-40 minutes, copper plate thicker, standing time should be longer, but holding time is also not more than four hours. 6, the pre-bake are printed on both sides, were the first face baked hot air circulation oven: temperature 75 ℃, time is 15-20 minutes, the second face hot air circulation oven: temperature 75 ℃, time is 25-30 minutes while printing on both sides while baking Hot air circulation oven: temperature 75 ℃, time is 25-40 minutes 7, stand 20 minutes after the plate is cooled to, but not more than 24 hours 8, 21 exposure exposure feet, sensitivity 9-13 9 grid, let stand for 10 minutes or more 10, the developing developing solution: 1wt% Na2CO3 solution spray pressure: 2.0-2.5kg / cm2 liquid temperature: 30 ± 2 ℃ imaging time: 40-90 seconds 11, after grilled HASL: 150 ℃ × 60 分钟 of gold plate, tin plate: 150 ℃ × 50 分钟 plug plates (in two steps): the first 75 ℃ × 120 minutes, and the second stage 150 ℃ × 60 分钟 Address: Guangzhou Panyu District, East Village tea tea Road 49 Website: www.youguangink.com Tel: 020-39219131 Fax: 020-39219130 customer service phone 15360001068 Miss Choi
