The BEST Pad Repair kit includes the tools and materials needed to reliably replace lifted or damaged surface mount and BGA pads on PCB's. This kit includes 3 different tin plated circuit frame patterns, which offer nearly 3 times as many useable replacement land patterns as other circuit frames. This kit can be had in either a dry film or epoxy versions for the pad and circuit trace repairs. In the dry film version a soldering iron and operator pressure make the connection while in the epoxy version a 2-part epoxy is mixed and applied to replacement pads and traces. The Pad Repair Kit includes (1) professional stainless steel tweezers, (1) Precision knife and (5) Orangewood sticks. This is a very versatile kit which will meet the needs of your BGA and other pad repairs.

The right instruction

BEST Inc. PCB repair artisans have been involved in board level repair for a combined 60 plus years. In addition, several BEST Inc. staff members have been teaching and contributing to the procedures found in the IPC 7721 Repair and Modification of Printed Boards and Assemblies. This combined experience is capture through a series of how to slides which will guide you through the actual repair procedures. These instructions provide advanced repair technicians some tricks of the trade which are key when performing PCB repairs.

Dry Film Adhesive System Clean and Fast

The BEST replacement circuit frames with dry-film adhesive backing make the repair process clean and neat. Simply trim out the circuit you need and bond it to the circuit board surface using heat and pressure

Epoxy Adhesive System – Proven Reliability

BEST testing has shown by using the BEST 2-part electronics adhesive system, the bond strength of repair traces, pads, and lands equals that of the original land, pads, and traces. Even under thermal air shock conditions from 50°c to 85°c at 30 minutes dwell time for 200 cycles this adhesive system performed well.

All materials are RoHs compliant

Why BEST PCB Repair Circuit Frames?
  • Stock to 5 business day delivery-every part of the process is controlled in house
  • Consistent quality all processing is done in house
  • Wide variety of materials- gold plate as well as both 1oz and 2oz copper with tin coating for RoHS compliance
  • Custom frames available as processing is done in house-saves your technician’s repair time, reduce the minimum order quantities and significant tooling charges and specialty tooling

The base metal is 1 oz copper with chemical etchant which allows for high bond strength to the PCB which will be repaired. The dimensions of the standard frames are 60 x 40 mm. The coating is on the PCB side is a shiny tin coating.

The film is a low stress epoxy film adhesive with a Tg at –60ºC. This minimizes the thermal stress on bonded parts during thermal cycling or shock testing from –55 to 150ºC. It is a clear 1mil (0.0254mm) in thickness nearly clear material. It has a shelf life 6 months minimum and is date-coded on the circuit frame to which it is bonded.

Specifications:
Frame Size:57 x 38 mm (2.25" x 1.50")
Material:Copper foil 0.036 mm (0.0014")-backside micro-etched for enhanced adhesion
Adhesive Backing:Phenolic film adhesive 0.0254 mm (0.001") thick.
Electrical Resistivity:Greater than 1014 ohm-cm
Dieletric Strength :750 Volts/mil
Glass Transition Temperature:-60º C
Device push off strength:Greater than 2,000psi, or 13.8N/mm2
Peel Strength:Greater than 9lbs/in (1.61 kg/cm) post cure to FR-4
Hardness:65 Type A
Cured density:1.2 gm/cc
Thermal Conductivity:1.2 BUT-in/hr-ft2-ºF
Linear Thermal Expansion:110 ppm/ºC
Max Continuous Oper Temp:150ºC
Bonding Time:15 seconds
Bonding Temperature:200ºC
RoHS compliance:YES
Shelf Life:6 months min. Circuit Frames are laser engraved with the expiration date.
Why BEST PCB Repair Materials?
  • Lead Free and RoHs Compatibility
    BEST Inc is the first provider of PCB repair kits to make sure that you can modify and repair lead free assemblies. The tin finish of the BEST circuit frames are "lead free compatible"; they are also compatible with eutectic alloy versions.
  • Flexibility to Meet Your Requirements

BEST can help you become more proficient at PCB repairs by offering a wide variety of tools to reduce the amount of time spent trimming circuit frames. Choose from a large variety of our different pads, traces, contact fingers and land patterns... or let us make a specialized version for you! We can turn these specialized patterns around for you quickly-as they are manufactured in house!

  • The right tools for the right job

       Because BEST PCB repair kits are designed by artisans who repair circuit boards for a living the right tools have been included in our PCB repair kit.

BEST Inc. PCB repair artisans have been involved in board level repairs for a combined 60 plus years. In addition, several BEST Inc staff members have been teaching and contributing to the procedures found in the IPC "7721 Repair and Modification of Printed Boards and Assemblies". This combined real life experience is captured through a series of "how to" slides which will guide you through the actual repair procedures.

  • Epoxy and Dry Film Circuit Frames - you have the choice!

    Dry Film Adhesive System- A Clean Way Damaged pads and traces can be replaced without the mess of liquid epoxy. The BEST replacement circuit frames with dry-film adhesive backing make this repair process clean and neat. Simply trim out the circuit you need and bond it to the circuit board surface using heat and pressure.

    The BEST dry film is superior to others as it is very clear making it easy for the repair technician to see what is going on to align the pad or trace to the PCB. In addition the BEST dry film is thinner than others making it sit on the PCB post repair closer in height to the original pads or traces making for a neater repair!

    If you are already using a dry film epoxy system see our competitive cross-reference chart here.
  • Epoxy Adhesive System- Proven Reliability

BEST testing has shown by using both backside micro etched circuit frames (a BEST standard) and the BEST 2-part electronics adhesive system that the bond strength of repair traces, pads and lands can approach that of the original lands, pads and traces. Even under thermal air-air shock conditions from -50 C to 85 C at a 30 minute dwell time over 200 cycles this adhesive system performed well. In a study summarizing a variety of adhesion techniques for the repair of printed circuit board traces, the 2 part resin-hardner epoxy system has been shown to yield the best results. Furthermore, another study demonstrated that the epoxy method yielded a greater part-pad shear strengths.
