Use Fort's Smart UV Debonding Selector. Find recommended debonding agents (L0-Gen-1 to LC0-Gen-5) and standard exclusion SOPs based on adhesive chemical type, brands, or pry hardness.

Smart UV Debonding Selector

This tool will guide you through 4 levels of steps to recommend the appropriate Fort debonding formula (L0-Gen-1 to LC0-Gen-5) and standard operating SOP based on your expertise.

Professional Notice: It takes time for adhesives to cure, and debonding is not an instant process.

Decision Tree Levels

1
Level 1: Adhesive Chemical Type Suitable for professional clients with a chemistry background
2
Level 2: Similar Adhesive Brands Suitable for clients who know the original adhesive model
3
Level 3: Cured Adhesive Hardness Suitable for clients testing via physical prying
4
Level 4: Standard Test Kit SOP If none of the above are identifiable, proceed with exclusion experiments

Level 1: Do you know the cured adhesive's chemical type?

If you have a chemical background or the spec sheet details the molecular structure, please select below:

Urethane Acrylate
Metha-acrylate
Epoxy-based (unfilled)
Epoxy-based (SiO2 Filled underfill)

Level 2: Do you know the adhesive's brand or model?

If you have the original adhesive packaging or know its manufacturer brand, please select below:

Norland Products NOA 65 (Pure UV cured)
Norland Products NOA 72 (Pure UV cured)
Epoxy Technology EPO-TEK® HYB-353ND
LOCTITE® EA-3335 (UV + Thermal cured)
Dexerials JD23A020 (UV + Thermal cured)
JE-526-1 (UV + Thermal cured)
EMIUV OPTOCAST 3410 Gen2 (with SiO2 spheres)

Level 3: Please use a needle tip to pry the cured adhesive and identify its hardness and touch

Apply force with the needle tip on the adhesive surface and observe the rebound and texture:

Soft The needle tip can easily penetrate, prying feels like a soft plastic pad, slightly elastic
Semi-Hard The needle tip leaves marks under pressure, prying feels like a plastic case, deforming slightly before break
Hard The needle tip is difficult to penetrate, prying feels like a hard plastic mask, very rigid
Extremely Hard Needle completely slips off, brittle upon prying, hardness and rebound similar to optical glass

Level 4: Cannot determine type or hardness? Use the Standard Test Kit

Don't worry! Fort RD Tech provides standard exclusion test kits. Please follow the SOP below to conduct checks and find the suitable formula:

1
Part Pre-treatment

Clear surface debris to restore the part to its physical initial state (e.g. FPC attachments on CIS boards).

2
Exclusion Test 1: Submerge in L0-Gen-1

Submerge the part under the liquid level of L0-Gen-1 at room temp for 0.5 to 2 hours. If it weakens and prys off easily, the adhesive is likely Urethane Acrylate; use Gen-1 for subsequent processing.

3
Exclusion Test 2: Submerge in L0-Gen-2 (Heated)

If no reaction, submerge a new part in L0-Gen-2, tighten the cap, and heat in a 40°C-60°C water bath for 2 to 6 hours. If it weakens, the adhesive is likely Metha-acrylate.

4
Exclusion Test 3: Submerge in L0-Gen-3 (Heated)

If still ineffective, submerge the part in L0-Gen-3, tighten the cap, and heat in a 50°C-80°C water bath for 4 to 16 hours. If it weakens, the adhesive is likely Epoxy (unfilled). (Precaution: May damage PC surfaces)

5
Exclusion Test 4: Silica-Filled Epoxy Underfill Test

If none of the above work, the adhesive is a highly rigid Epoxy/SiO2 filled underfill. Choose based on surrounding heat tolerance:
Surrounding parts tolerate 100°C: Submerge in L0-Gen-4, seal, and heat in a 80°C - 100°C water bath for 24-96 hours.
Surrounding parts sensitive to heat: Apply LC0-Gen-5 drip-resistant cream locally, isolate, and bake at 80°C-100°C for 24-96 hours.

Fort Standard Test Kit Specification: Includes L0-Gen-1 to L0-Gen-4 bottled solvents (100ml each), LC0-Gen-5 drip-resistant cream (50g), and Gen-0 cleaning solvent. Welcome to contact us to request a kit or sample testing.
