F-E3T UV STENCIL

F-E3T UV STENCIL

Product Breakdown

This product is a “UV stencil,” which is a distinct category from a standard reballing stencil. Here’s what that means:

• UV Stencil: This tool is designed to be used with a UV-curable solder mask, often referred to as “green oil.” The stencil has apertures that align with the pads on the motherboard or chip. A technician applies a liquid solder mask through the stencil and then uses a UV light to quickly cure and harden the material. This process is used to:

   

  • Repair Damaged Pads: Rebuild or reinforce solder pads that have been lifted or damaged from a PCB due to a previous repair or physical stress.
  • Prevent Short Circuits: Re-apply the solder mask to prevent bridging or short circuits between pads.
• F-E3T: This is a specific model identifier for the stencil. It is part of a series of stencils from manufacturers like AMAOE or JTX, which are well-known in the micro-soldering and mobile device repair industry. The “E3T” model number signifies that it is designed for a particular type of component, often an eMMC, NAND, or power management IC, but the exact component is not specified in the search results for this model.

Purpose and Application

This tool is essential for professionals in a variety of electronic repair fields, including mobile devices, automotive electronics, and computer motherboards.

• • Core Function: It enables a technician to perform a crucial pre-reballing step. Before a new or reballed chip can be placed on a board, the board’s surface must be in perfect condition. This stencil ensures that the pads are properly insulated and ready to accept the new solder balls.
  • Why It’s Needed: It is used in complex repair scenarios where a simple reballing is not enough. The UV stencil provides the precision necessary to repair micro-scale damage that would otherwise make a board unusable.

     

  • Target Audience: This product is intended for skilled technicians and micro-soldering professionals who have the necessary equipment, such as a microscope, a UV lamp, and UV-curable solder mask.
• Net Quantity: 1

FEATURES:

SOLDER MASK REPAIR GREEN OIL UV STENCIL

EACH STENCIL IS PROOFREAD ACCORDING TO THE ORIGINAL FACTORY DRAWINGS TO

ENSURE THAT EVERY SOLDER JOINT MUST NOT BE MISSING, COMPLETELY CONSISTENT WITH PRECISE ALIGNMENT

HIGH PRECISION, NO BURRS, SO THAT EACH OF YOUR MESH HOLES CAN BE OF THE SAME SIZE AND NOT STUCK TIN BALLS

HOW TO USE:

AFTER CLEANING THE MOTHERBOARD OR CHIP PART, DRY IT WITH AN AIR GUN TO KEEP IT DRY

USE A BLADE TO APPLY AN APPROPRIATE AMOUNT OF CURING GREEN OIL PARALLEL TO THE CHIP OR MOTHERBOARD THAT NEEDS TO BE REPAIRED

PAY ATTENTION TO APPLYING THE GREEN OIL AS EVENLY AS POSSIBLE, THE THINNER THE COATING, THE BETTER, TRY NOT TO HAVE AIR BUBBLES WHEN LAMINATING

THEN PUT THE GREEN OIL STENCIL (THE PRINTED SIDE) DOWN AGAINST THE PADS, AND THE PADS ON THE GREEN OIL NET ARE ALIGNED WITH THE PADS ON THE CHIP OR THE MOTHERBOARD.

ACCORDING TO THE THICKNESS OF THE APPLIED GREEN OIL, IT IS CURED BY THE PURPLE LIGHT EMITTED BY THE PURPLE LIGHT LAMP FOR 6-15 SECONDS

CLEAN THE PAD PART WITH PCB WATER OR ALCOHOL, AND THEN CONTINUE TO USE THE CURING LAMP TO CURE IT FIRMLY, THAT IS, COMPLETE THE QUICK REPAIR OF THE CHIP OR MOTHERBOARD PAINT DROP
