Ding Chang PCB is stripping blue plastic, TP-03 
 Ding Chang TOPSUN can peel the blue plastic, can be interpreted as the glue can be peeled off (ink), was also called peelable ink, peelable adhesive name it is a blue sticky silk-like screen printing ink, and its main feature is exhausted after a hand or a tool to easily peel, without the residues in the substrate above, the most widely used application is the circuit board PCB in a tin oven, wave soldering, reflow can effectively protect cheat and do not need to solder the place will not be solder and traditional methods is the use of high temperature adhesive tape (textured paper) manually paste it into the board, and then been to weld, but this process is: paste by hand, time-consuming, inefficient, and most important point is in the after wave soldering or reflow, the tear tape usually there will be some residue on the board and even less from the perspective of cost-saving science. Ding Chang peelable blue glue quality and PETERS quality comparable to 

 ? Ding Chang stripping blue plastic has the advantage of 
 1 printed circuit board PCB industry in general: screen printing, 
 2 curing methods: the case of heat-curable inks, the required oven, tunnel furnace and other heating equipment in the conditions of 150 degrees 30 minutes can be easily solidified. 
 High temperature performance: the blue plastic cured from the low temperature tens of degrees to 280 degrees can afford. Company peelable blue glue can withstand up to 280 degree heat. (TP-03 for the wave soldering-specific resistance, temperature of 265 degrees), (TP-07 green), (TP-09 blue) are high temperature resistant, at the same time 2 wave soldering, hand-dip tin furnace, HAL, over 1-4 times reflow resistance temperature of 280 degrees, reflow for paragraph 3, paragraph 6, paragraph 8, paragraph 10 temperature zones. ) 
 Easy to peel: high temperature after the blue plastic coating is more easily stripped, toughness will also strengthen the hand can be easily remove without any residue, no secondary cleaning 
 Environmental efficiency: peelable blue glue the last of this is to remove, so not worried about environmentally friendly, peelable blue glue provided by the company through the ROHS Directive standards, and provide SGS report 

 ? Ding Chang PEELABLE the blue plastic technology parameters 
 1, screen mesh size requirements: 18 ~ 24T nylon screen printing, silk screen blue plastic requires printing plastic surface is smooth, uniform thickness. (Also available steel mesh, aluminum printing) 
 Blue plastic, the thickness of the printed: printed once 200 400vm (0.2 to 0.4mm after drying), the thickness after drying should not be less than 0.2mm, printed secondary 400 ~ 1000vm (0.4 ~~ 1mm), the dry thickness not should be less than 0.4mm. A: Indian secondary process: the first printing for the first time the blue plastic 150 ° C oven and bake for 10 minutes, the roast before printing technology blue gel. 
 3, Blue rubber curing temperature and time: such as the use of printed once a blue plastic process, then the oven in the case of constant temperature of 150 ℃, and bake for 30 minutes, such as the use of printed secondary blue plastic process, the oven at a constant temperature of 150 ℃, bake 45 to 50 minutes. 
 , Blue plastic spray tin process: tin stove in the case of 240 to 280 ℃, immersion tin time control in 10 seconds, usually not more than 15 seconds for the ideal process, the hot air temperature: 330 ℃ to 400 ℃ hot air pressure: 2.5 ~ 4.5KG / cm 3. 

 ? Ding Chang peelable blue glue to use 
 A: 18 to 24T of the mesh on the PCB printed on the appropriate thickness of the blue plastic coating 
 : Will be printed on a blue plastic plate directly into the oven to 150 degrees (temperature) and bake about 30 minutes. Curing coating has a high temperature conditions, but in order to better stripping, it is recommended after after wave soldering or reflow soldering and then remove (toughness strengthen, reduce the peel strength), if necessary, but also can directly remove 
 Remarks: 
 A peelable blue glue is required before using the tool for uniform mixing in order to increase its mobility and uniformity. 
 In the printing process, the speed of the pass as far as possible to reduce the angle of the scraper is raised to about 60 to 70 degrees. 
 There are holes in the case of PCB printed on blue plastic. Note: the blue plastic injected into the hole thickness of not more than two thirds of its otherwise drying will form a rivet, it is difficult to peel and plug the aperture. 
 If there needs must use the stencil printing, the stencil can be used directly, but still recommended to use screen printing to achieve the best local solder mask effect. 
 5 Please do not add any thinner, such as the need to adjust the sticky silk can directly request the company in the production process to adjust the process of using.
