J-STD-004B: A New Twist on an Old Standard?
This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. Many procedures have colour illustrations to help the user understand the guide. This revision has been critically reviewed for downliad and accuracy.
A must for all quality assurance and assembly h, IPC-A illustrates industry-accepted workmanship criteria for electronics assemblies through full-colour photographs and illustrations. This section includes procedures common to rework, repair and modification. Users can insert company specific procedures, or remove just the pages needed for a specific job to help keep the workbench clear.

This guide includes everything needed for repair and rework of electronic assemblies and printed circuit boards! European Environmental Standards EN address test methods and thresholds for halogen content. IPC-A is invaluable for all inspectors, operators and trainers.
Readability and usability were improved based on user feedback from the original release. More info Test methods and criteria for metal content, viscosity, slump, solder ball, tack and wetting of solder pastes are included. Nothing has changed there.
How did you hear about AIM? Rosins are plant products and are subject to more natural variation than resins; str are commonly used in newer flux formulations due to their more consistent performance. Skip to main content. It references test methods and criteria for metal content, viscosity, slump, solder ball, tack and wetting of solder pastes.
J-STDB: A New Twist on an Old Standard? | AIM Solder
This standard lists requirements for qualification and characterization of solder paste. J-STD was updated about five years ago, but the comingling of designations from the old A and new B revisions in industry literature has created much confusion among users. Part 2 is IPCB and the procedures include tools, materials and methods to be used in removing and replacing surface mount and through-hole components. Part 1 General Requirements has also been updated for ease of dowhload and provides important direction and guidelines for all procedures.
This Revision has full-colour pictures and illustrations — nearly new.
Non-ionic halogenated compounds, or halogens for short, are sometimes wtd to improve the stability of fluxes and are the subject of environmental watch lists. Flux designation has three components. IPC standards address test methods and thresholds for halide content.
Lists requirements for qualification and characterization of solder paste. More info Make sure your operators, inspectors, and engineers have the most current industry consensus information. Most of these tests remain the same, but two important ones have changed.
Understand the subtle differences between rosin and resin. Table 1 summarizes the changes. The definitive illustrated guide to printed circuit board acceptability!
The expiration of the RoHS exemptions is driving most downloadd the industry to Pb-free materials and processes. This single volume includes all previously published changes and several new procedures for BGAs including reballing and flex-print repair.
The terms are often used interchangeably, but rosin is a naturally occurring substance, and resin is either a modified rosin or completely synthetic material.
