Some preparations to be done before PCBA wave soldering
Do you know the process flow of wave soldering? It is a very critical link in the entire PCBA production process. If this step is not done well, then all the front-end efforts are useless and a lot of energy is needed for maintenance. So how do we control the wave soldering process? As the saying goes, the plan is the first, and the action is the last; we have to plan and prepare before we start. The following Baiqiancheng Electronics will share some preparations before PCBA wave soldering. Work.

Some preparations to be done before PCBA wave soldering

Wave soldering

1. Check the PCB to be soldered (the PCB has been coated with SMD glue, SMC/SMD SMD glue and solidified and completed the THC insertion process) and whether the solder resist is applied to the soldering surface of the socket of the component and the gold finger and other parts Or stick it with high temperature resistant tape to prevent the socket from being blocked by solder after wave soldering. If there are large-size slots and holes, they should also be attached with high-temperature tape to prevent the solder from flowing to the upper surface of the PCB during wave soldering. (The water-soluble flux should be a liquid solder resist. After coating, place it for 30 minutes or bake under a light for 15 minutes before inserting the components. After soldering, it can be washed directly with water.)

2. Use a density meter to measure the density of the flux. If the density is too high, dilute it with a thinner.

3. If using traditional foaming flux, pour the flux into the flux tank.

The above are the preparations that the editor has to analyze with you before the wave soldering factory. The three steps mentioned above are also the work that must be done before the entire wave soldering. These are also the SMT chip processing factories should be in In the process control, it is the first to be written in the process file. If you want to process in Shenzhen PCBA, you can contact us.

We are not an agent
Our factory is located in China. For decades, Shenzhen has been known as the world's electronics R&D and manufacturing center. Our factory and website are approved by the Chinese government, so you can skip the middleman and buy products on our website with confidence. Because we are a direct factory, this is the reason why 100% of our old customers continue to purchase on iPCB.
No minimum requirements
You can order as little as 1 PCB from us. We will not force you to buy things you really don't need to save money.
