This application provides a caviar-encased cheese popping pearl and its preparation method. The caviar-encased cheese popping pearl includes popping pearl particles and a protective liquid. The popping pearl particles include an inner core and a colloidal solution. The inner core includes the following components in the indicated mass percentages: calcium lactate 1%-2%, calcium chloride 0.05%-0.1%, white sugar 20%-30%, guar gum 0.01%-0.03%, xanthan gum 0.1%-0.2%, gellan gum 0.01%-0.05%, cream cheese 10%-20%, citric acid 0.2%-0.4%, and caviar 2%-5%, with the balance being water. By using a combination of xanthan gum, guar gum, and gellan gum, caviar can adhere to popping boba particles using the compounded colloids. Gellan gum provides good viscosity and gel strength. When used in combination with xanthan gum and guar gum, the viscosity of xanthan gum has a synergistic effect on the entire colloid system. By controlling the amount of guar gum, xanthan gum, and gellan gum, the adhesion of caviar particles can be ensured, while preventing excessive gellan gum from hardening the surface of the popping boba and ensuring the taste of the finished product.

The application discloses a manufacturing process for improving the solder mask bridge falling problem of a high-layer circuit board based on an AI server, relates to the field of PCB manufacturing technologies, and comprises a pretreatment process, a silk-screen printing process, a pre-baking process, an exposure process, a developing process and a high-temperature curing process. The pretreatment process adopts volcano ash plate grinding and super-rough cleaning. The silk-screen printing process adopts secondary printing of oil, and the first solder mask bridge position is blocked from oil. The exposure process reduces the gap between the solder mask bridge and the design PAD and etching PAD. The developing process maintains the pH value of developing liquid at a constant value by calculating the ink usage of a single PCB and adopting the drag tank method or the production green oil plate method, so that the problems of the prior art, such as the easy falling of the solder mask bridge and the high defect rate, are solved.
