The main difference between the display of a smartphone with touch control from analogs is the presence of a touchscreen that provides control of the device. In case of factory assembly errors, the touchscreen disappears. This is especially true for cheap models. How to glue the touchscreen on Chinese phones?
In production, a sealant is used to solve the problem. He will preserve the sensitivity to touch and leave no traces. Therefore, it is important to use similar mixtures outside of production.
Both glue and tape
What kind of glue to glue the smartphone screen? There are several composition options that allow you to attach the touchscreen to the case without special skills, even at home:
- epoxy;
- Loca;
- silicone;
- film;
- double scotch tape for touchscreen;
- B7000.
Epoxy glue is good in that negative consequences will not occur even if the composition gets on the board. You can use the composition not only for the display, but also for fastening the small parts of the smartphone.
Loca's specialized compound firmly glues the display to the touchscreen glass. There is only one requirement: ultraviolet light is needed for solidification.
One of the most popular options is silicone glue. It is only necessary to carefully and accurately apply the composition to the surface, filling all the voids.
The simplest fastening method is called scotch tape. It is convenient to glue even body parts with double-sided tape. Nothing interferes with displaying information on the display after repair. Even a novice Lego master can handle repairs. The only problem is that not all manufacturers meet expectations.
It is a good idea to repair specific models with film. You can use the device right after the repair without warming up the screen. The only difficulty is choosing a film for the gadget model or cutting it to fit the size of the wheelbarrow.
Cold welding
Ultraviolet glue welds the surface. However, even the slightest mistake in the gluing procedure gives irreparable consequences. The composition has an undeniable advantage, transparency. At the junction, the glue is invisible. You need a small lamp, even a flashlight will do.
Since the composition becomes plastic only under the influence of high temperatures, then you will have to act quickly and accurately. After cooling down, it will be impossible to separate the structure.
- The inoperative or cracked glass of the wheelbarrow is removed.
- The display surface is cleaned.
- The glue is applied to the entire surface. The excess is removed by rolling after 10-15 seconds.
- A touchscreen is installed and the resulting structure is rolled with a roller.
- Remove excess glue with a toothpick.
- The compound is treated with ultraviolet light until complete polymerization.
- Leave for a day to transform the composition into a monolith.
Even after a few minutes, the glue hardens so that it is indistinguishable from the factory assembly.
The simplest way to work with B7000 is to heat the screen. After heating and separating the glass, check the uniformity of the glue application. There should be no voids.
You can choose a good option only in a specialized store. B7000 glue is ideal. But you can successfully replace it with B5000 or B6000. The first has long been used by craftsmen in the repair of electronics, and the second helps to restore jewelry.
Film is a simpler option, but it is difficult to find the right sizes or a universal option.
Double-sided acrylic tape works best for repairs. But it also costs more. How to properly glue 3m double-sided tape: evenly, without bubbles and oblique overlays. They'll ruin everything.
- Before working with a thin double-sided tape for phones 3m, it is imperative to degrease the surface, which must then be fixed.
- Leave the parts to dry for 10-15 minutes.
- Adhesive tape is evenly applied to the display. It should fit snugly to the surface.
- After fixing, you can use a building hairdryer to speed up the gluing.
Factory sealant is not the only way to connect the parts of a gadget. Renovations are easy to do at home. You need to believe in yourself and use trusted sources to purchase original glue.
