IPC/ECA J-STD-002C Error NEW!
In the Acknowledgement page of this printed document, the incorrect Chair of the ECA Soldering Technology Committee was shown. 
The hyperlink details the error and the recommended pen and ink corrections needed.

IPC J-STD-003B Error NEW!
In clause 3.5.1 Solder Temperatures, the nominal temperature to be utilized for tin/lead solderability testing is correctly defined as 235°C (the primary metric).  The secondary metric of this nominal temperature (that is, the temperature converted to the Fahrenheit scale) incorrectly appears as 473°F.  The correct conversion is 235°C = 455°F.

The correction of this nominal temperature conversion has been inserted into the electronic versions of IPC J-STD-003B in May 2007 and will be incorporated into all subsequent hard copy printings of this standard.  For those hard copies of IPC J-STD-003B that show this temperature conversion error, the user is advised to make the pen and ink correction in accordance with their company’s document control program.

IPC-7526 New!
IPC-7526  Stencil and Misprinted Board Cleaning Handbook
Cleaning of stencils and misprinted PCBs has taken an increasingly important role in surface mount technology. Fine and ultra-fine pitch lands, together with other advanced packages, place new demands on stencil cleaning. Paste volume is a critical issue for fine, ultra-fine, chip-scale, BGA and flip-chip components. Insufficient solder due to clogging of stencil apertures is a primary cause of defects. The purpose of this handbook is to provide a basic understanding of stencil/misprint cleaning processes.

IPC-9151B New!
Printed Board Process Capability, Quality, and Relative Reliability (PCQR²) Benchmark Test Standard and Database

Many printed circuit board buyers have developed internal processes to evaluate the capabilities of their printed circuit board manufacturers companies. Manufacturers often receive multiple requests from multiple customers to manufacture test panels as part of qualification procedures. The PCQR² program provides an industry standard for the design of these benchmark process capability test panels. The data resulting from this process provides database subscribers with the ability to review detailed results from individual manufacturers and to compare the capabilities of multiple fabricators across the industry. This document describes this process for evaluating the manufacturing capability of key attributes specified in the design and acceptability standards controlled by IPC. Revision B addresses new assembly simulation profiles.
