Quality control is deeply rooted in our PCB assembly and box build manufacturing processes. Your PCB components are the heart of your electronics, making reliability, safety, longevity, performance consistency, and compliance pillars of our service that are non-negotiable.
Nothing is more important to us than focusing on electronic product quality control and PCB quality control. Our reputation is built on the pursuit of the highest standards.
We believe in continuous improvement and keeping up with the latest industry standards, which puts us at the forefront. We work proactively to meet delivery requirements and customer expectations.
High standard Quality
SJCEMS is a specialist manufacturer of high reliability PCB assemblies with longer lifecycles and fail-proof quality, with a production team who are all IPC-A-610 trained and certified.
All products are manufactured and supplied to IPC -A-610 Class 3 standard and every board is inspected individually. Our team does not batch inspect any of our products and we pursue our first-time pass rate.
IPC-A-610 includes both Class 3 and Class 2 criteria. Class 3 encompasses electronic products and devices designed for critical and demanding operational conditions, where consistent and reliable performance is imperative. These applications, such as life support systems or flight control mechanisms, cannot tolerate downtime and must perform when required. Printed circuit boards falling within this classification are well-suited for situations demanding a high level of assurance and essential functionality.
Certifications
ISO 9001 is a globally recognised standard for quality management. we are committed to implementing and maintaining manufacturing and other processes, as well as the continuous training of our team, to reliably deliver an impeccable level of quality of products and services every time.
SJCEMS also complies with the following regulations:
Restriction of Hazardous Substances (RoHS)
Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH)
By adhering to RoHS and REACH during the assembly of all of our products and services, SJCEMS actively contributes to protecting human health and the environment from the risks posed by chemicals and harmful substances involved in electronics manufacture.

Effective and Efficient Procurement
To maximise the performance of your electronic product, our in-house purchasing team ensures all components meet the standards previously defined within the pre-manufacture specification.
Electronics procurement is not easy. Developing and maintaining strong working relationships with an array of suppliers, our procurement specialists hand pick the most appropriate supplier for the range of components or manufactured items that are to be purchased. We have a supplier group blacklist and whitelist. In the whitelist supplier group, we know the unique advantages of each supplier.
We have continual access to industry specialised software containing global stock availability, enabling us to forecast and reduce lead times and cost wherever applicable.
Monitoring
Performance is monitored internally on a daily/weekly basis. We have a number of key performance indicators (KPIs) in place across all departments. When thresholds are met or trends acknowledged, action is taken to review areas that are considered to be under-performing or not meeting our expectations.
