Sales and Quoting
Manufacturing, stock and capabilities
Once all componentry has been received, the average lead time for manufacture can be between 2-4 weeks depending on batch quantity and number of components per assembly.
Componentry lead time in the current supply market generally varies from existing stock to 52 weeks in extreme cases. The lead time will be advised at the time of quotation, taking in consideration the lead time for components and the manufacture time.
PCB Quality Control
Surface Mount Technology (SMT) and Through Hole Assembly
|Through Hole assembly||Surface Mount Technology (SMT)|
|Popularity||More prevalent in the assembly of larger electronic components, such as transformers, connectors, semiconductors and electrolytic capacitors.||The most widely used PCB assembly process. Most available electronic components can be mounted on circuit boards using this technology.|
|Process||Manual process but can also be automated. Pre-formed components are threaded through pre-drilled holes and soldered onto circuit boards, either by hand or using an automated process.||Fully automated process. Components are pasted and soldered to circuit boards, using fully automated production lines.|
|Features||Higher rated components are sometimes available compared to the surface mount counterparts.||Can be used to place components on both sides of a circuit board and it removes the need to drill holes through the PCB.|
|Advantages||Provides a more robust mechanical bond between the circuit board and the application which enhances strength and security, making it ideal for aerospace and defence applications, within equipment that withstands extreme stress and temperatures. It also has a fast and uncomplicated prototyping.||Perfect for the assembly of smaller, lighter, and more powerful PCBs that require a high degree of customisation. It also provides a greater uniformity of component soldering and allows for greater control of the width of route traces, which in turn reduces mechanical heat and noise, therefore improving the quality and performance of a product.|
