Silicone screen printing Ichiban detection
Firstly, the network marks the phenomenon will appear in the screen printing process, then the more common phenomenon, net mark will lead to silicone keys in the screen surface is not complete, usually occurs mainly due to net mark is used in printing ink fluidity insufficient, silicone screen printing may also be coarse mesh net production and became a step, just select the good liquidity of the ink and the choice of smaller mesh network silk screen either.
In addition, the printing process will be more links in the screen there is the case of the emergence of bubbles, often generally relatively large screen characters appear similar cases, the main reason silicone silkscreen printing appears too fast, uneven screen scraper efforts, silicone keypad surface is not clean, the ink quality is poor, uneven viscosity itself, the main approach to general solution is the main reason to solve, if it can be cleaned silicone keys uneven surface caused by the screen if it is too fast, scraper the intensity is uneven, then focus on those aspects, if it is of poor quality ink, you can imagine increase defoamers and anti-foaming agent can increase the viscosity of the ink itself.
We see a lot of silicone key products, the surface will have a character imprint, silicone screen printing little understanding of people know by silicone button printing process can achieve, silk screen process mainly to the product or letters printed up some text, but in the printing process often there will be some special cases, the following Bo Hao Electronics take everyone to understand the condition can occur when silicone keypad screen process.
