FAQ
TL;DR: "Personally, I put only cut org in this model and give a little B7000 on the edges." Poor prep or liquid‑only glue caused failures in 1–2 weeks on S7‑class OLEDs. Use die‑cut tape first, then minimal edge glue if needed. [Elektroda, blahfff, post #17551231]
Why it matters: For DIYers and repair techs choosing between B7000 and OEM tape, this clarifies when, where, and how to bond screens securely without stressing OLEDs.
Quick Facts
- B7000 skins in approx. 3–6 minutes; full cure typically 24–48 hours. [Zhanlida B-7000 Adhesive TDS]
- Galaxy S7 approach: use original die‑cut adhesive; add small B7000 beads top and bottom; leave sides untouched. [Elektroda, blahfff, post #17551231]
- Avoid any tape or glue under the LCD; it hinders work and alignment. [Elektroda, seba1601, post #17550774]
- Factory Samsung panels often include pre‑applied tape that’s usually sufficient; avoid loose aftermarket tape and add B7000 if needed. [Elektroda, seba1601, post #17550774]
- Near buttons/sensors/cameras, apply the least possible adhesive to prevent ingress. [Elektroda, seba1601, post #17551098]
Should I use B7000 glue or double‑sided tape for a phone screen?
On thin OLED modules like the Galaxy S7, install original die‑cut tape. Optionally add a small bead of T7000 on the top and bottom edges. Avoid liquid‑only gluing to reduce stress damage risk. Do not add any adhesive under the display. [Elektroda, blahfff, post #17551162]
Is the factory adhesive on Samsung screens enough, or should I add glue?
Factory‑applied tape on original Samsung panels is usually sufficient. Some techs still add B7000, because generic tape sometimes lets go. If your seller included separate tape, skip it and use B7000 instead. [Elektroda, seba1601, post #17550774]
Can I put thin tape in the middle under the display for support?
No. Do not place tape under the LCD. It hinders work and can obstruct correct seating. This often makes future service harder. [Elektroda, seba1601, post #17550774]
Where should I apply B7000 on a Galaxy S7 or similar OLED?
Apply a little B7000 only on the top and bottom edges. Leave the sides untouched. Use original die‑cut tape for the main bond. [Elektroda, blahfff, post #17551231]
How much glue near the home button, sensors, and cameras?
Use the least possible adhesive in those areas. Keep glue out of unintended zones. Thin, controlled lines reduce seepage and sensor issues. [Elektroda, seba1601, post #17551098]
How long does B7000 take to set and fully cure?
B7000 skins over in about 3–6 minutes. It typically reaches full cure in 24–48 hours. Avoid load or flex before full cure. [Zhanlida B-7000 Adhesive TDS]
Is it safe to glue thin OLEDs using only liquid adhesive?
No. Use the original, cut double‑sided tape instead. Optionally add a small T7000 bead on the top and bottom edges. “They are delicate and can damage them if they are stressed.” [Elektroda, blahfff, post #17551162]
My replacement came with separate double‑sided tape. Should I use it?
Avoid loose aftermarket tape included by sellers. Use B7000 alone instead if no factory tape is present. Prefer factory‑applied adhesive when available. [Elektroda, seba1601, post #17550774]
Should I stack extra tape layers to increase thickness?
No. Use the original, correctly‑thick die‑cut tape for your model. Do not add extra tape or glue under the display. [Elektroda, blahfff, post #17551162]
What if the frame is warped or I didn’t clean it well?
Poor prep or a warped frame can create stress points and later damage. Some screens failed after one to two weeks. Correct frame issues before bonding. [Elektroda, blahfff, post #17551231]
For Galaxy A5 (A500), is glue or tape better?
If you’re bonding the display assembly to the housing, you can skip the original tape. Apply glue so it holds firmly to the frame. [Elektroda, Pedros050, post #17550655]
Can I combine factory tape and B7000 for extra hold?
Yes. When a Samsung panel ships with factory tape, a thin bead of B7000 can improve adhesion. Apply carefully to avoid squeeze‑out. [Elektroda, seba1601, post #17551210]
Quick how‑to: reattach a Galaxy S7 display without stressing it
- Fit the original die‑cut adhesive kit to the frame.
- Seat the display and apply a little B7000 on the top and bottom edges.
- Leave the sides alone; hold light pressure until the initial set. [Elektroda, blahfff, post #17551231]
