User manual 3M PRINTED CIRCUIT BOARD

[. . . ] Application Profile Market: Electronic Account Type: Printed Circuit Board Assembly Application Description Bonding and protecting through-hole components in the printed circuit board assembly operation. PRODUCT 3MTM VHBTM (Very High Bond) 4932, 4936 and 4941 Tapes Application Method For best results, clean the surface first with mix of isopropyl alcohol and water (50/50 mix). Note: Follow the solvent manufacturer's precautions and directions for use when handling solvents. REGION North America SIC 3672 ­ Printed Circuit Boards 3571 ­ Electronic Computers Key Application Requirements Ability to absorb and damp vibrational energy, and withstands IR reflow temperatures. Benefits/Advantages To Customer Shock resistant: 3MTM VHBTM Tapes have the ability to absorb energy during impact which can help protect component leads. [. . . ] The vibration and impact to which electronic devices can be subjected can often damage delicate leads and sever the electrical connection on components. 3MTM VHBTM double coated acrylic foam tapes have been used to bond electronic components in printed circuit board assembly. 3M VHB's ability to absorb and damp vibrational energy has become increasingly important to the design engineer. There are a variety of potential applications for 3M VHB and 3M acrylic foam tapes in PCB assembly. Bond and help stabilize large integrated circuits on the board. Bond a smaller board subassembly to the larger board. Attach a battery to the back of a component or directly to the board. Attach a stiffening or mounting bracket to the board. Product 3MTM VHBTM Acrylic Foam Tape 4932 and 4936 3MTM VHBTM Acrylic Foam Tape 4941 Thickness (0. 025" or 0. 64 mm) Advantages Die-cuttable acrylic foam construction provides excellent shock, vibration, and solvent resistance. The flexibility of 3M VHB tapes tolerate thermal expansion on many irregular surfaces. This die-cuttable acrylic foam construction provides greater thickness and flexibility of thinner 3M VHB tapes.
