材料の適合性を検証するにあたり、業界では種々のテストビークルが存在し活用されている。IPC-B-52試験基板は実生産で用いられる材料と工程を具体的に表現したものであり、イオンクロマトグラフと表面絶縁抵抗(SIR)の両試験のニーズを満たすテストビークルである。IPC-9203Aに示す規格はIPC-B-52テストビークルに対応し、製造工程の評価や、選択した製造材料セットと工程が清浄度の観点から適合しているという客観的証拠を提供する場合に利用できる。またIPC-9203Aに示すユーザーガイドラインはIPC-9202の手引き文書として作成されており、製造者が材料と工程の適合性を実証する場合の規定「~することが望ましい」と「~すること(する必要がある)」という点について明確に提示している。
概説 本書、IPC-9202A「材料・工程の特性評価/認定試験の方法」は、プリント回路組立品(PCA)の代表的なサンプル上の表面絶縁抵抗(SIR)の変化を記録するものである。この試験は、はんだ付後に外層に残るはんだ由来のフラックスまたはその他の工程残さが原因で不要な電気化学的反応を引き起こし、信頼性に重大な影響を及ぼす可能性について定量化するものである。 この試験では、実際の生産工程において電子回路の代表的なものとなるような基板をテストビークルとして使用する。これは、定量的かつ定性的なデータの両方を得ることができる試験である。 IPC-9202Aに紹介する試験は、提案された製造工程や工程変更を用いた場合に、生産するハードウェア(製品)の最終的な性能が電気化学的リスクに対し許容可能であるということを示すための「工程認定」用として使用することができる。工程変更には組立工程の手順...

IPC-2591 version 1.2 (CFX) standard establishes the requirements for the omni-directional exchange of information between manufacturing processes and associated host systems for assembly manufacturing. IPC-2591 version 1.2 (CFX) standard applies to communication between all executable processes in the manufacture of printed board assemblies, automated, semi-automated and manual, and is applicable...
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...
This document provides tests that record changes in surface insulation resistance (SIR) on a representative sample of a printed circuit assembly. It quantifies any deleterious effects that might arise from solder flux or other process residues left on external surfaces after soldering, which can cause unwanted electrochemical reactions that grossly affect reliability. It uses test vehicles that...
The IPC-2591v1.3 standard establishes the requirements for the omni-directional exchange of information between manufacturing processes and associated host systems for assembly manufacturing. This standard applies to communication between all executable processes in the manufacture of printed board assemblies, automated, semi-automated and manual, and is applicable to related mechanical assembly...
While there are a variety of industry test vehicles for the examination of materials compatibility, most available test boards leave something to be desired as there is often a dramatic difference in materials between such test boards and produced assemblies. A test vehicle was needed which could be used for both ion chromatography and SIR testing that would be more representative of mainstream...

IPC-HERMES-9852 an open industry standard, developed by The Hermes Standard Initiative and approved by IPC, provides a state-of-the-art communication protocol for machine-to-machine communication between equipment units in electronics assembly lines for surface-mount technology (SMT). Thus IPC-HERMES-9852 represents a next generation standard to the technology documented in IPC-SMEMA-9851...
The lack of a uniform component traceability standard has caused an unnecessary consumption of resources (e.g., time, people, money, etc.) to track events or parts to their sources and to remedy any quality, reliability, etc., issues. Lack of a standard has also made it difficult to uniformly create and appropriately enforce the necessary contracts. This standard establishes minimum requirements...
Surface mount pad cratering typically initiates prior to detection by existing electrical monitoring test methods. There are limited instrumentation techniques that are currently available that can identify non-electrical damage and its location to a high degree of accuracy. This guideline document establishes an acoustic emission (AE) method to evaluate the performance and reliability of surface...
The purpose of this standard is to provide requirements and best practices for EMS companies to ensure protection of intellectual property for their customers. By using this standard, EMS companies can provide their customers assurance that the intellectual property built into their circuit boards is protected. The document is also a companion to IPC-1071 for printed circuit board manufacturers...
