Manufacturing Process

Parks' manufacturing process begins with RECEIPT.


In this area, all the company's raw materials are checked, validating quantities, serial numbers, values, etc. After the conference, all raw materials receive their own Parks code, with the aim of ensuring that all components are traceable throughout the product's life.

Upon receipt, all raw materials will be stored in the WAREHOUSE area. In this area, the ERP used by Parks knows exactly where the raw material can be found.

Components sensitive to temperature and humidity receive a differentiated treatment at this time, going through the Backing stage in a climatic chamber with temperature and humidity control and, later, being stored in a Dry Box with humidity control below 2%.

The production process begins with the creation of a Production Order (PO) coming from Production Planning and Control (PCP).

This PO contains the product to be assembled, the quantity of parts and the date of delivery to the customer.

At this time, the Warehouse delivers all the raw materials needed to produce a given product to Production.

Production is responsible for receiving this raw material, checking that everything is correct, setting up the components in the feeders and placing them in the machines, in order to start the Production Process.

The assembly of the electronic boards in the production line starts with the solder paste printer, called Printer. The function of this machine is to apply the Solder Paste on the Printed Circuit Board (PCB). The deposition of the solder paste is done with a stencil, a kind of template, where the designer shows where the solder paste needs to be applied. It is on this paste deposition that the components will be placed. Before the PCB leaves the printer, it performs a 2D evaluation in the most critical regions of pulp deposition indicated by the operator. If any deviation appears, the machine does not release the PCI and signals to the operator where it found the problem.

Not necessarily necessary, but helping the printer, we have a machine called Solder Paste Inspector (SPI). The purpose of this machine is to monitor the quality and repeatability of the paste applied by the Printer. If a deviation occurs, the SPI signals the printer so that it can correct itself. There are offline machines that do the same thing, but disconnected from the production line, which can serve several production lines at the same time.

The next machine in the Production Process is called a Component Inserter, or Pick And Place. The purpose of this machine is to place the SMT (Surface Mount Technology) components of the project (resistors, capacitors, inductors, memories, connectors, etc.) on the board, in order to create a PCBA (Mounted Printed Circuit Board).

After inserting the components, the automated part of the process ends with the passage of this assembled board through the Refusion Furnace, whose objective is to solder the components on the PCBA. This machine has numerous heating zones, controlled by a Programmable Logic Controller (PLC), whose objective is to maintain the temperature of each zone as close to the setpoint as possible, through the control and monitoring of resistances and blowers. A differential in Parks ovens is the monitoring of the exhaust gases, interrupting the operation of the oven if the exhaust stops.

After the Remelting Furnace, there is a machine called PCBA Inspector, or, in English, AOI (Automatic Optical Inspection). This machine, like the SPI, is also not mandatory on the line, and serves to verify, through the comparison of ideal images, how the assembly of the PCBA was. Usually this machine is used in complex projects, boards with large amounts of components.

Now the PCBA is ready to be complemented manually, placing components called THT (Through Hole Technology). Components that cross the board and that must be welded manually, either by people or by a welding machine.

The Production Process now goes to the part of INTEGRATION and FINAL TESTS. These processes practically work together.

In INTEGRATION, the PCBA is placed inside the final packaging of the product, and the product is closed, ready for sale.

The TESTING area at Parks is responsible for testing 100% of production, using our own test jibs or those supplied by our customers. No product leaves Parks without being tested. After approval, the product is packed in anti-static packaging and made available to the SHIPMENT area, which is responsible for sending the products to our customers.
