Forehead temperature gun circuit board PCBA processing

PCBA working principle of forehead temperature gun circuit board

When the infrared forehead thermometer is aligned and close to the measured object to the effective distance detected by the sensor, press the power/measure button and hold it for several seconds, then the infrared sensor module inside the infrared forehead thermometer will collect the temperature and convert it It is an electrical signal, and then the electrical signal is converted into a digital signal, and then transmitted to the single-chip microcomputer through the interface. The single-chip microcomputer collects the current ambient temperature and performs corresponding temperature compensation processing on the transmitted temperature digital signal and transforms it into the temperature value of the measured target.

The non-contact infrared forehead temperature gun PCBA solution is implemented by Microchip's ultra-low power consumption technology and a low-cost 8-bit PIC® microcontroller integrated with LCD control functions. It includes a power supply module, a button module, an infrared sensor module, a temperature sensor (module), and signal conditioning., Voice module, speaker and LCD display module.

Forehead temperature gun circuit board PCBA processing needs to provide information

1. Complete PCB board-making documents (Gerber files, placement diagrams, steel mesh files) and board-making requirements;

2. Complete BOM (including model, brand, package, description, etc.);

3. PCBA assembly drawing.

PS: To report the PCBA function test fee, the PCBA function test method shall be provided.

PCBA processing flow of forehead gun circuit board

1. Customer orders

Customers place orders according to their actual needs, PCBA processing plants, and put forward specific requirements. The processing plant will evaluate its own capabilities to see if it can complete the order. If the manufacturer determines that it can complete the order within the expected time, then the two parties will negotiate to determine the production details.

2. Customers provide production materials

After the customer decides to place the order, he provides a series of documents and lists to the PCBA processing factory, such as the PCB electronic files, coordinate files, and BOM lists required for production, which must be provided.

3. Procurement of raw materials

PCBA processing plants purchase relevant raw materials from designated suppliers according to the documents provided by customers.

4. Incoming Material Inspection

Before PCBA processing, all raw materials to be used are subjected to strict quality inspection to ensure that they are qualified and put into production.

5. PCBA production

During PCBA processing, in order to ensure the quality of production, whether it is patch or solder production, manufacturers need to strictly control the furnace temperature.

6. PCBA test

The PCBA processing plant conducts strict product testing, and the PCB boards that pass the test are delivered to the customer.

7. Packaging after sale

After the PCBA processing is completed, the product is packaged and then delivered to the customer to complete the entire PCBA processing work.

How much does PCBA processing cost for the forehead gun circuit board?

PCBA processing cost of temperature gun circuit board = PCB board cost + PCB testing fee + PCB engineering fee (for small batches) + component purchase cost (partially up by 5%) + SMT/DIP welding fee + PCBA testing fee + assembly engineering fee (Applicable for small batches) + special packaging and logistics costs (if customer needs).

How long does it take to process the PCBA of the forehead gun circuit board?

The time composition of PCBA processing of the forehead gun circuit board: component procurement and PCB production + SMT chip processing + DIP plug-in processing + PCBA testing + finished product assembly.

Forehead temperature gun circuit board PCBA processing time details: components and PCB procurement are generally placed at the same time, PCB production requires 3-10 days, component procurement 2-15, the arrival time of components is relatively uncertain, SMT and DIP takes 3-5 days in total, PCBA test generally takes 1-3 days, and finished product assembly takes 2-5 days.
