Zot Assembly Division has invested in state-of-the-art equipment to offer SMT placement up to 24000cph from 01005 to 56mm x 56mm devices supported by vapour phase and reflow ovens, AOI and X-Ray inspection.

All operators are trained to IPC610 for PCB assembly and IPC620 for electro-mechanical assembly. Complete testing is accomplished by highly trained engineers and technicians supported by a full range of NAMAS calibrated test equipment.

Project management and NPI/DFM

Utilising Zot’s unique combination of manufacturing divisions places Zot in a position to offer seamless services and resources for any new project. As a team, Zot can advise on bare PCB production guidelines and suitability for production placement and population. Zot can advise on sheet metal and machined assemblies to achieve best cost manufacture. Our Materials group will offer best possible costs for commercial material and offer low-cost alternatives if required.


The expertise within Zot partnered with the latest equipment and technology allows for a professional quick turnaround prototyping service which is often required for new product introduction. This is achieved by utilising our state-of-the-art SMT machines. Zot has Specialist Operators who can hand solder a wide range of Through Hole and SMT components.

Surface mount technology

Zot has 3 MyCronic machines for SMT placement from 01005 discreet devices to 56mm x 56mm devices. This gives a total SMT placement capability of 64000cph. A conveyor system automatically takes the PCB through solder paste printing (DEK Horizon 03i) to SMT population and then either automatic convection (BTU VIP70A) or vapour phase (Ascom VP1000-66) reflow. Products are inspected using AOI (ALeader ALD770Pro) and X Ray (UNICOMP AX8200).

Through-hole Assembly

Zot operates a yearly training course schedule to train all PCB operators to Certified IPC 610 Specialist status. Production is complimented with detailed manufacturing aids to ensure correct component placement.

Wiring and electro-mechanical assemblies

Zot operates a yearly training course schedule to train all Electro-mechanical operators to Certified IPC 620 Specialist status. Wire crimping is carried out using manual or automatic crimping tools depending on technology and quantity. For instance, thermal strip tools are used for single stranded PTFE cable. Cables looms can be manufactured using pin boards or chassis wired if required. Efficient and accurate assembly process is controlled by manufacturing aids and assembly fixtures where required. All operators are trained for paintwork and mechanical inspection.


Zot has an extensive test department which can test and debug all customer products if required. We also operate as a Customer Service department for some customers where ageing returns can be updated to the latest material issue, reworked and software updates implemented. This can also incorporate assemblies that have not been previously manufactured by Zot.

Any level of functional testing and Boundary Scan testing can be developed and carried out. This includes development and manufacture of test jigs and fixtures. All test equipment is calibrated to NAMAS standards.


Material is controlled by our MRP system which ensures firm control of cost and deliveries. To support customer products through their lifecycle and beyond, our supply base uses local, regional and global suppliers. To ensure we provide the customer with the required level of performance, our suppliers performance is measured, evaluated regularly and benchmarked against their competition. With various partnerships, Zot is able to hold suppliers accountable for lead-times through buffer agreements to allow us to be flexible and lean. Material is stored in a secure, air conditioned ESD environment. This contains 3 Kardex 24 shelved machines kitted out with antistatic boxes and sensitive components are stored in humidity chambers. Material control is operated in a first-in-first-out method with full traceability of all parts.
