Yes, this repair procedure is described in the IPC-7711/7721 standard. The maximum size of a delamination depends on the product class. This is described in the IPC-A-600, the IPC-A-610 and IPC-6012 standard.
Yes, the repair procedure is described in the IPC-7711/7721. The maximum contamination of gold-plated edge contacts is described in the IPC-A-600 and the IPC-A-610 standard.
AABUS is the abbreviation of “As Agreed Between User and Supplier”. This abbreviation often occurs in an IPC standard.
IPC has 3 product classes: class 1 (consumer electronics), class 2 (industrial electronics) and class 3 (high reliability electronics). The customer may determine the product class in which the product must be produced. It is important that the inspector knows [...]
Yes, IPC has made a product classification in every standard, including the IPC-7711/7721. This product classification is as follows: IPC-7711/7721 Class 1 - General electronic products (e.g. consumer electronics, these are products where the main requirement is the function of [...]
The IPC-7711/7721 training is both a theory but above all a practical training. In the theory module, mainly Chapter 1 of the book is discussed. In practice, the participants learn how to solder wires together (splicing), how to solder and [...]
Nitrogen is known in machine soldering, but not yet in hand soldering. Hakko invented this. If you hand-solder with nitrogen, it is much easier than without nitrogen. The soldering tip does not oxidize (closed nitrogen atmosphere), the solder wetting is [...]
The melting point of lead-free solder is approximately 217 °C. But you cannot solder at this temperature! The soldering temperature should be approximately 100 ° C above the melting point. That means a total temperature of 317 °C. You also [...]
In the 7721 part of the IPC-7711/7721 is described how you can repair a plated through hole. Usually you use a eyelet / funnelet for this. There are special repair kits with which you can easily fix this. This is [...]
In the 7721 part of the IPC-7711/7721 it is described how you can repair a conductor/track. For example with a wire, or with a repair kit (frame with or without adhesive). How this is done is trained in the practical [...]
